platform/x86:intel/pmc: Enable the ACPI PM Timer to be turned off when suspended
...
Allow to disable ACPI PM Timer on suspend and enable on resume. A
disabled timer helps optimise power consumption when the system is
suspended. On resume the timer is only reactivated if it was activated
prior to suspend, so unless the ACPI PM timer is enabled in the BIOS,
this won't change anything.
The ACPI PM timer is used by Intel's iTCO/wdat_wdt watchdog to drive the
watchdog, so it doesn't need to run during suspend.

platform/x86:intel/pmc: Call pmc_get_low_power_modes from platform init
...
In order to setup a table of low power mode requirements for Meteor Lake,
pmc_core_get_low_power_modes() will need to be run from platform init code
so that the enabled modes are known, allowing the use of the
pmc_for_each_mode helper. Make the function global and call it from the
platform init code.
