This driver is for devices attached to a PCIe root port that support
Runtime D3. It creates the necessary PowerResource in the root port to
provide _ON/_OFF methods for which will turn off power and clocks to the
device when it is in the D3cold state.
The mainboard declares the driver in devicetree and provides the GPIOs
that control power/reset for the device attached to the root port and
the SRCCLK pin used for the PMC IPC mailbox to enable/disable the clock.
An additional device property is created for storage devices if it
matches the PCI storage class which is used to indicate that the storage
device should use D3 for power savings.

Replace the two obsolete LPID implementations with the new PEPD device.
The PEPD device gets included in the plaforms' `southbridge.asl`, since
it is required to load the `intel_pmc_core` module in Linux, which
checks for the _HID. (See CB:46469 for more info on that.)
There is no harm for mainboards not supporting S0ix, because the _DSM
function won't be called with the LPS0 UUID on such boards. Such boards
can use the debugging functionality of `intel_pmc_core`, too.

Windows does not comply with the Low Power Idle S0 specification and
crashes with an `INTERNAL_POWER_ERROR` bluescreen when function 1, does
not return at least one device constraint, even when function 1 is
announced as being not available by the enum function. Returning an
empty package does not work.
At least the following Windows versions were verified to be affected:
- Windows 8.1 x64, release 6.3.9600
- Windoes 10 x64, version 1809, build 17763.379
- Windows 10 x64, version 1903, build 18362.53
- Windows 10 x64, version 2004, build 19041.508
- Windows 10 x64, version 20H2 / 2009, build 19042.450
To make Windows work on S0ix-enabled boards, return a dummy constraint
package with a disabled dummy device.
Since the device constraints are only used for debugging low power
states in Linux and probably also in Windows, there shouldn't be any
negative effect to S0ix. Real device constraint entries could be added
at a later point, if needed.
Note: to fully prevent the BSOD mentioned above the LPIT table is
required on Windows, too. The patch for this is WIP, see CB:32350.
If you want to test this, you need to applie the whole ACPI patch
series including the hacky LPIT test implementation from CB:47242:
https://review.coreboot.org/q/topic:%22low_power_idle_fix%22

CSE RW blob which will be used by coreboot to update CSE's RW partition,
is packed part of FW_MAIN_A and FW_MAIN_B. This will increase the size of
FW_MAIN_A and FW_MAIN_B. So, accordingly load and hash calculation of
FW_MAIN_A (or FW_MAIN_B) increases during verstage. It increases the boot
time by around 300ms.
The patch address the boot time by pulling CSE RW blob outside of
FW_MAIN_A and FW_MAIN_B. So, it creates new FMAP region within
RW_SECTION_A and RW_SECTION_B and adds CSE RW blob in the new regions
(ME_RW_A and ME_RW_B) as a CBFS file.

The UID property is removed. This value is not the same as the port
number; according to some docs it should be unique but it is not fully
clear what it should be tied to. Regardless, it is not used by the
Thunderbolt driver in the kernel.
I also renamed some functions/structures to be clear that this is just
an ACPI driver for the PCIe root port and not a driver for the root port
itself. As part of this I removed the PCI based resource operations and
the scan bus function since this device does not have children itself.
Finally I added a detailed comment with an example describing what the
driver is for and what properties it generates.
TEST=boot on volteer and ensure the USB4 root port device and properties
are added to the SSDT as described by the comment in chip.h.

The USB4 host interface (DMA) devices need to use SA_DEVFN_*
instead of SA_DEV_* when determining the ACPI name.
The matching names are removed from the SOC-level ACPI name
handler since they are provided by this driver now.

Due to platform-specific constraints, it is not possible to enable DPR
by programming the MCH's DPR register in ramstage. Instead, assume it
has been programmed earlier and check that its value is valid. If it is,
then simply configure DPR in TXT public base with the same parameters.
Note that some bits only exist on MCH DPR, and thus need to be cleared.
Implement this function on most client platforms. For Skylake and newer,
place it in common System Agent code. Also implement it for Haswell, for
which the rest of Intel TXT support will be added in subsequent commits.
Do not error out if DPR is larger than expected. On some platforms, such
as Haswell, MRC decides the size of DPR, and cannot be changed easily.
Reimplementing MRC is easier than working around its limitations anyway.

msr_set_bit can only set single bits in MSRs and causes mixing of bit
positions and bitmasks in the MSR header files. Thus, replace the helper
by versions which can unset and set whole MSR bitmasks, just like the
"and-or"-helper, but in the way commit 64a6b6c was done (inversion done
in the helper). This helps keeping the MSR macros unified in bitmask
style.
In sum, the three helpers msr_set, msr_unset and msr_unset_and_set get
added.
The few uses of msr_set_bit have been replaced by the new version, while
the used macros have been converted accordingly.
