Currently, EC wake signal (GPIO_24) is configured early on in

really required to be configured until ramstage. This change moves
GPIO_24 configuration to happen in ramstage.

This change updates the pad configurations for wake lines as
follows:
1. Pen eject wake signal needs to be configured as PAD_WAKE i.e. wake
using GPIO controller block. This is because pen eject signal is not
dual routed and the trigger filtering is set by the kernel driver
differently for S0 and S3 wake. Hence, it cannot use SCI GEVENT and
instead has to fall back to using GPIO controller wake.
2. All other wake signals (EC, trackpad, fingerprint) need to be
configured as SCI. This allows OS to enable/disable wake from these
sources if required. Example: powerd disables wake from trackpad when
in tablet mode. Hence, all other wake sources use SCI.

This function was copy-pasted, comments included, from Sandy Bridge.
However, it is only called with 0x0044 as the northbridge's PCI ID.
Therefore, `bridge_silicon_revision() & BASE_REV_MASK` will always
evaluate to 0x40, which never equals `BASE_REV_SNB`, that is, 0x00.
As the condition is always false, treat this code as dead and drop it.
Following a similar reasoning, all direct comparisons against SNB
steppings will always be true, because `bridge_silicon_revision()`
returns at least 0x40 which is always larger than either `SNB_STEP_D0`
or `SNB_STEP_D1`. So, drop all but the code path that is actually used.

Tested:
- configs that don't need futility don't test for pkg-config, so it's
not required for them.
- failing pkg-config test leads to the message
- working pkg-config test leads to a successful build

Vboot determines openssl through pkgconfig, so pointing its build
system to /bin/true makes the build not break unless it needs to use
valid information about openssl.
Vboot's use of openssl is only for some special features, mostly around
PKCS key format parsing and not needed by cbfstool. While cbfstool
can link vboot, it can't link with openssl because openssl's license
is deliberately incompatible with the GPL.

A late change went into v3+ of reference schematics which inverted
EN_PWR_WIFI to meet PCIe reset/power timings for WiFi device. This is
incorporated into v3.51+ for Trembyle reference and v3.2+ for Dalboz
reference. However, some variants are built with v3+ reference
schematics, but without the inversion of EN_PWR_WIFI polarity. Thus,
we need to add support for following combinations:
1. Pre-v3 Schematics
2. V3+ Schematics
3. V3+ Schematics + Active low wifi power
This change adds a new Kconfig
`VARIANT_MIN_BOARD_ID_WIFI_POWER_ACTIVE_LOW` that sets the minimum
board ID that has EN_PWR_WIFI active low in hardware. Variants that
missed this change in V3+ integration (berknip and vilboz) have board
IDs set to VARIANT_MIN_BOARD_ID_V3_SCHEMATICS + 1. For others, this
defaults to VARIANT_MIN_BOARD_ID_V3_SCHEMATICS.

This change configures PCIE_RST1_L as GPO driven low on the sleep
path. This is required to keep PERST# asserted to devices until
coreboot deasserts it on S3 resume path. Without this change, on S3
resume, PCIE_RST1_L gets deasserted sooner than required resulting in
violation of PCIe reset timings.
With this change, the behavior of PCIE_RST1_L is as follows:
1. GPIO27 is configured as NF (PCIE_RST1_L) in coreboot
bootblock/romstage and driven high.
2. On S3 entry, GPIO27 is configured as GPO driven low.
* Boot out of G3: Timing should be met since GPIO_27 is pulled down by
default until coreboot configures it.
* S3 resume: Timing should be met since GPIO_27 is configured as GPO
low and it retains state across S3 entry/exit. So, should be low
until coreboot configures it.
* Warm reset: Timing should be met since it is configured as NF. So,
hardware guarantees the reset timing as seen in "warm reset.jpg" in
#46.

from the call. This results in a double free.
Split the implementation into two steps, one that ones and one that
frees. This is easier to understand and fixes the bug.
Note: This likely has no effect in coreboot since it doesn't seem to
have a proper free() implementation. But it might gain one one day.

This change clears interrupt and wake status for a pad when
configuring it. This ensures that stale interrupts/wake notifications
are flushed out and do not cause spurious wakes in future suspends.

`flags` field of soc_amd_gpio structure is set only for SCI and SMI
configurations. This change adds a new helper macro
PAD_CFG_STRUCT_FLAGS that allows setting of all soc_amd_gpio members
including `flags` field. This can be used directly by PAD_SCI and
PAD_SMI. For all other pad configurations, PAD_CFG_STRUCT macro uses
PAD_CFG_STRUCT_FLAGS with flags set to 0. This allows dropping of
redundant parameter 0 for flags for all other pad configurations.

Currently, for Stoneyridge and Picasso mainboards, pads that are
configured for SCI/SMI/WAKE need to have multiple entries in the
configuration table - one for PAD_GPI and other for the special
configuration that is required. This requires a very specific ordering
of pads within the table and is prone to errors because of conflicting
params provided to the different entries for the same pad. This also
does not work very well with the concept of override GPIOs where the
entry in base table is overridden with the first matched entry from
the override table.
This change updates the way GPIO configuration is handled for special
routing like SCI/SMI/WAKE/DEBOUNCE by setting the control field of
soc_amd_gpio structure in the macros performing these
configurations. Also, program_gpios() is updated to perform a write to
GPIO control register instead of read-modify-write. This is because
mainboard is expected to provide only a single configuration entry for
each pad within a given table. Thus, there is no need to preserve
earlier configuration.
Mainboards that were providing multiple entries for a single pad are
updated accordingly.

Some codepaths want to set selected bits of a hardware register
to match those of a given variable in memory. Provide a helper
function for this purpose and use it in gpio_set(),
gpio_input_pulldown() and gpio_input_pullup().
This change also adds GPIO_PULL_MASK and updates GPIO_OUTPUT_MASK to
include all bits dealing with pull and output respectively.

This change adds helper macro PAD_CFG_STRUCT for setting the fields
of `soc_amd_gpio`. Additionally, macros are added for different
operations i.e. pull, output, trigger, int_enable, event_trigger,
wake_enable, debounce, etc. All GPIO configuration macros are updated
to use PAD_CFG_STRUCT instead of setting the fields directly.
