Enhanced Intel SpeedStep Technology (EIST) and Intel Speed Shift
Technology (ISST) - also know as HWP - are two independent mechanisms
for controlling voltage and frequency based on performance hints.
When HWP is enabled, it overrides the software-based EIST. It does not
depend on EIST, though, but can be enabled on its own.
Break up that currently existing dependency in ACPI generation code.
It was tested that HWP can be enabled and gets used by the Linux pstate
cpufreq driver. With HWP disabled, the frequency does not decrease, even
not in powersave mode. After enabling HWP the frequency changed in
relation to the current workload. (Test device: Acer ES1-572)

This sets the state of GSPI chip select to 1 (deasserted) as applied
by the FSP during the silicon init phase. GSPI 0 and 1 are set to CS
mode manual in the SerialIoGSpiCsMode section which means we need to
explicitly configure CS to deasserted in the SerialIoGSpiCsState
section. GSPI0 is the CR50 and GSPI1 is the fingerprint sensor. We
were running into problems where the normal expected CS toggle
sequence to wake up CR50 did not work because CS was already asserted
when it was expected to be deasserted, leading to TPM timeouts.

PMC support was not enabled on Xeon_sp platforms. This involves turning
on SOC_INTEL_COMMON_BLOCK_PMC and then adding the proper hooks in SOC
specific code. This patch leverages code from the Skylake project and
adds the bare minimum hooks to leverage PMC common code. Most
importantly this enables power management registers located in the PMC
device (under ACPI_BASE_ADDRESS). Access to this device is also needed
for SMM setup and handling.
TEST=build for Tiogapass and enable the following Kconfig options:
select SOC_INTEL_COMMON_BLOCK_PMC
select ACPI_INTEL_HARDWARE_SLEEP_VALUES
select CPU_INTEL_COMMON_SMM
Boot the system and ensure pmbase is programmed. (Look for pmbase in

debug messages (search for "Enabling SMIs") and verifying in HW by

trying to ask *why* this change was necessary -- the pins move in
mysterious ways and all we can do is watch and wonder. Pin 30 is now
used for a new camera reset GPIO... surely, there must have been some
excellent reason why that pin couldn't just have become pin 52 instead.
