[Aaron Durbin (Code Review)]

to look at the new patch set (#2).

soc/amd/common: add single function ACPI PM1 GPE helpers

The existing code in common/block/acpi is mixing multiple operations:
saving things to cbmem in common code but then soc code uses that
information, reliant upon soc-specific struct soc_power_reg object,
and only saving/snapshotting ACPI registers very deep in ramstage.

To unwind the above provide some functions that are more targeted:
- Add struct acpi_pm_gpe_state object
- Add acpi_fill_pm_gpe_state()
- Add acpi_pm_gpe_add_events_print_events()
- Add acpi_clear_pm_gpe_status()

BUG=b:159947207
