The S3/S4 workaround is specific to Panther Point stepping A0, and it is
wrongly implemented. Rewrite the whole function as per reference code.
Since this runs in SMM, be overly cautious and double-check everything.
Do not rely on GNVS to determine if xHCI is enabled. Instead, check
whether the corresponding bit in the Function Disable register is set.
Only Panther Point has xHCI, so exit early if this is not the case.

Add support for the Intel LPIT table to support reading Low Power Idle
Residency counters by the OS. On platforms supporting S0ix sleep states
there can be two types of residencies:
* CPU package PC10 residency counter (read from MSR via FFH interface)
* PCH SLP_S0 assertion residency counter (read via memory mapped
interface)
With presence of one or both of these counters in the LPIT table, Linux
dynamically adds the corresponding attributes to the cpuidle sysfs
interface, that can be used to read the residency timers:
* /sys/devices/system/cpu/cpuidle/low_power_idle_cpu_residency_us
* /sys/devices/system/cpu/cpuidle/low_power_idle_system_residency_us
The code in src/acpi implements generic LPIT support. Each SoC or
platform has to implement `acpi_fill_lpit` to fill the table with
platform-specific LPI state entries. This is done in this change for
soc/intel/common, while being added as its own compilation unit, so SoCs
not yet using common acpi code (like Skylake) can use it, too.

They can be written to multiple times but cannot be modified after
being locked, which happens during FspSiliconInit. Because coreboot
populates subsystem IDs after SiliconInit, these devices specifically
must be written beforehand or will otherwise be locked with their
default values of 0:0.
Tested by checking lspci output on System76 galp3-c (WHL), oryp5 (CFL),
and oryp6 (CML).

While FORCE_PWR is set high, it prevents retimer from entering low power
state. S0ix failure occurs while USB4 Gatkex is connected on Port-0.
This change sets FORCE_PWR(GPP_H10) low. This FORCE_PWR GPIO will be
toggled by kernel through DSM method while updating retimer firmware.
