Rename LPID to PEPD for consistency. PEPD means "Power Engine Plug-In
Device" and is the name Intel and vendors usually use, so let's comply.

Move the UUID to the condition, since there is no need to assign a name
when it is only used once. Also add a comment to make clear that the
functions inside that condition are only used by the Low Power Idle S0
functionality, while the PEPD in general can be present on boards
without S0ix capability, too. For details check CB:46469.

The various platform BARs are not always the same size across different
SOCs, so use the defined size rather than a hardcoded value.
This results in the following change on TGL which increased the MCHBAR
size to 128K:
-system 00:00: [mem 0xfedc0000-0xfeddffff] has been reserved
+system 00:00: [mem 0xfedc0000-0xfedc7fff] has been reserved
And fixes the following error output from the kernel:
resource sanity check: requesting [mem 0xfedc0000-0xfedcdfff],
which spans more than pnp 00:00 [mem 0xfedc0000-0xfedc7fff]

This SOC overrides the common PMC device and instantiates the PMC device
in the SSDT. It needs to call the common PMC function to provide the
IPC mailbox method.

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.

Currently the decision of whether or not to use mrc_cache in recovery
mode is made within the individual platforms' drivers (ie: fsp2.0,
fsp1.1, etc.). As this is not platform specific, but uses common
vboot infrastructure, the code can be unified and moved into
mrc_cache. The conditions are as follows:
1. If HAS_RECOVERY_MRC_CACHE, use mrc_cache data (unless retrain
switch is true)
2. If !HAS_RECOVERY_MRC_CACHE && VBOOT_STARTS_IN_BOOTBLOCK, this
means that memory training will occur after verified boot,
meaning that mrc_cache will be filled with data from executing
RW code. So in this case, we never want to use the training
data in the mrc_cache for recovery mode.
3. If !HAS_RECOVERY_MRC_CACHE && VBOOT_STARTS_IN_ROMSTAGE, this
means that memory training happens before verfied boot, meaning
that the mrc_cache data is generated by RO code, so it is safe
to use for a recovery boot.
4. Any platform that does not use vboot should be unaffected.
Additionally, we have removed the
MRC_CLEAR_NORMAL_CACHE_ON_RECOVERY_RETRAIN config because the
mrc_cache driver takes care of invalidating the mrc_cache data for
normal mode. If the platform:
1. !HAS_RECOVERY_MRC_CACHE, always invalidate mrc_cache data
2. HAS_RECOVERY_MRC_CACHE, only invalidate if retrain switch is set

The option `HeciEnabled` was partly replaced by use of the device on/off
state in the devicetree in commit 3de90d1. The option has been removed
from the corresponding boards, so `HeciEnabled` is always 0 and ME
always gets disabled during soc finalize, when `HECI_DISABLE_USING_SMM`
is set.
Replace the option in the finalize function by the same dt state check
that sets the FSP option and drop the remaints of `HeciEnabled`.
Devicetrees still having `HeciEnabled` have been adapted to keep the
current behaviour.

Currently, the ACPI PM timer state gets set in devicetree by the option
PmTimerDisabled. However, it is not board design dependent. Thus, add a
user-selectable Kconfig option.
Disabling the PM ACPI Timer is only valid when PM Timer emulation is
supported and is only possible, when there is a hardware PM Timer (APL
does not have one for example). SoCs, where the hardware PM Timer can be
disabled must select `PM_ACPI_TIMER_OPTIONAL`.
This new Kconfig gets used in the follow-up commits of this series.
