The GPIO pin map for CNL-H does not match with the OS expected
pin numbers. This has been updated to match what is used by the
Linux kernel pinctrl driver and the pad base has been set for
the GPIO groups to match the sparse GPIO map used by the kernel.
I do not have CNL-H hardware to test this so it is verified against
the kernel driver at drivers/pinctrl/intel/pinctrl-cannonlake.c

The GPIO drivers in Windows and Linux for the Cannonlake CPU
have a sparse GPIO map and do not allocate pins contiguously.
Each GPIO group is allocated as 32 pads regardless of whether
the hardware actually has that many in the group.
It appears this originated with a bug in Windows/UEFI and was
carried over to Linux in order to work with existing firmware:
https://lore.kernel.org/patchwork/patch/855244/
In order to support using ACPI GPIOs it is necessary for coreboot
to be compatible with this implementation. The GPIO groups that
are usable by the OS are declared with a pad base which is then
used to compute the number for ACPI GPIOs.
BUG=b:120686247
TEST=tested with write protect GPIO on sarien board. Before this
change the ACPI pin number was 220 which did not correspond to the
pin number in Linux. After this change the ACPI number is 303,
which maps to the correct GPIO in Linux. Now the GPIO value reported
by the kernel changes when the WP pin is toggled in hardware.

In some situations the GPIO pad numbers used by the OS are not
contiguous and coreboot must provide a way for ACPI to provide
the expected GPIO number to the OS.
To do this each GPIO group can now have a pad base value, which
will be used as the starting pin number for this group and it
is added to the relative pin number of this GPIO to compute the
ACPI pin number for a particular GPIO.
By default this change has no effect because the existing uses
of INTEL_GPP() will set the pad base to PAD_BASE_NONE and the
GPIO number is used as the ACPI pin number without translation.

When building coreboot from scratch with 'make -j4', I sometimes see

It happens, I think, because the rule generated by
cbfs-files-processor-defconfig runs 'make savedefconfig', which builds
build/util/kconfig/conf, and something also builds it, at the same time.
Fix this case, by making this rule depend on $(objutil)/kconfig/conf.
The same fix is also precautiously applied to the rule for
$(KCONFIG_AUTOHEADER) in Makefile.

will reprogram the GPIO settings after FSP-S step so they are correct
when the OS attempts to use them.

The code is based on autoport and that for T430s
Tested:
- CPU i5-3337U
- Slotted DIMM 2GiB
- Soldered RAM 4GiB from samsung (There may be more models here)
- Camera
- pci-e and usb2 on M.2 slot with A key for wlan
- sata and usb2 (no superspeed components) on M.2 slot with B key for wwan
- On board SDHCI connected to pci-e
- USB3 ports
- libgfxinit-based graphic init
- NVRAM options for North and South bridges
- Sound
- Thinkpad EC
- S3
- TPM1 on LPC
- EHCI debug on SSP2 (USB3 port on the left)
- Linux 4.9.110-3 within Debian GNU/Linux stable, loaded from
Linux payload (Heads), Seabios may also work.
Not tested:
- Fingerprint reader on USB2 (not present on mine)
- Keyboard backlight (not present on mine)
- "sticky_fn" flag in nvram
Not implemented yet:
- Fn locking in nvram (may not be identical to "sticky_fn")
- C-based native graphic init (since T431s has eDP instead of LVDS)
- Detecting the model of Soldered RAM at runtime, and loading the
corresponding SPD datum (3 observed) from CBFS (the mechanism may be
similar to that on x1_carbon_gen1 and s230u, but I do not know how
to find gpio ports for that, and SPD data stored in vendor firmware.)

Provide rise/fall times as measured on existing boards. This will
need adjusted for new boards but provides a starting point that
makes I2C clocks look reasonable.
Tested by measuring I2C bus speed and rise/fall times with a scope.

Add an entry to the soc_clock table for a 216MHz clock so that
the I2C controller clock is calculated correctly when the I2C
bus is used in coreboot.
This was tested by measuring the I2C clock speed on H1 I2C bus
on a sarien board in coreboot and ensuring it is ~400KHz.

The input clock for the I2C controllers was set at 133MHz but should
really be 216MHz according to the kernel:
https://patchwork.kernel.org/patch/10408729/
"Intel Cannon Lake PCH has much higher 216 MHz input clock to LPSS I2C
than Sunrisepoint which uses 120 MHz. Preliminary information was that
both share the same clock rate but actual silicon implements elevated
rate for better support for 3.4 MHz high-speed I2C."
This change was tested on a sarien board where an I2C trackpad that was
measuring ~700MHz on I2C and is now measuring ~380MHz.
