This change ports some previous work for Skylake:
cb58683ef5 soc/intel/skylake: Add support for mode-aware DPTF
...to common DPTF code so that we can support mode-aware DPTF for other
Intel platforms.
BUG=b:138702459
BRANCH=none
TEST=Manually test on hatch:
(1)Add DPTF_TSR0_TABLET_PASSIVE and DPTF_TSR1_TABLET_PASSIVE
to hatch baseboard dptf.asl
(2)Flash custom EC FW code which updates DPTF profile number when
entering/exiting tablet mode
(3)On DUT, see /sys/class/thermal/thermal_zone2/trip_point_{1,2}_temp
updated when device mode is switched (tablet/clamshell)

Some timeouts given were too small when serial console is enabled due to
its spinlock making code runtime worse with every AP present.
In addition we usually don't know how long specific code runs and how
long ago it was sent to the APs.
Remove the timeout argument from mp_run_on_all_cpus and instead wait up
to 1 second, to prevent possible crashing of secondary APs still
processing the old job.
Tested on Supermicro X11SSH-TF.

with a single function.
Add possibility for the platform to skip these if

IMC is found on certain Xeon processors. On such platforms SPDs are not
connected to SMBus on PCH but to dedicated IMC-owned pins. The purpose
of this driver is to expose access to the i2c/smbus controller associated
with IMC.
Datasheet used: Intel Xeon Processor D-1500 Product Family, Volume 2,
reference 332051-001
This driver is largely based on i2c-imc.c Linux driver.

This is a consolidation of the respective feature in `soc/intel/*lake/`,
including additional support for MAINBOARD_POWER_STATE_PREVIOUS.
For the latter, firmware has to keep track of the `previous` state. The
feature was already advertised in Kconfig long ago, but not implemented.
SoC code has to call pmc_set_power_failure_state() at least once during
boot and needs to implement pmc_soc_set_afterg3_en() for the actual
register write.

Currently SPI bus id is used to map to the controller in order to set
the controller state. In certain platforms SPI bus id might not be
exactly the same as GSPI bus id. For example, in Intel platforms SPI bus
id 0 maps to fast spi i.e. SPI going to the flash and SPI bus id 1 .. n
map to GSPI bus id 0 .. n-1. Hence using SPI bus id leads to mapping to the
GSPI controller that is not enabled. Use the GSPI id bus so that the right
controller is set to active state. This fixes the regression introduced
by CB:34449

Add explicit CBMEM_STAGE_CACHE option. Rename
CACHE_RELOCATED_RAMSTAGE_OUTSIDE_CBMEM to TSEG_STAGE_CACHE.
Platforms with SMM_TSEG=y always need to implement
stage_cache_external_region(). It is allowed to return with a
region of size 0 to effectively disable the cache.
There are no provisions in Kconfig to degrade from
TSEG_STAGE_CACHE to CBMEM_STAGE_CACHE.
As a security measure CBMEM_STAGE_CACHE default is changed to
disabled. AGESA platforms without TSEG will experience slower
S3 resume speed unless they explicitly select the option.

Add an API to check if device is a LPSS controller. This API can be
used for IRQ assignments for LPSS PCI controllers, since the LPSS
controllers have a requirement of unique IRQ assignments and do not
share same IRQ# with other LPSS controllers.
SOC code is reponsible to provide list of the LPSS controllers
supported and needs to implement soc_lpss_controllers_list API,
in case it needs to use this common implementation.
