Revert "soc/intel/adl: Drop SGPM, RGPM and EGPM methods"

This reverts commit 1399442289607acc5203fb12df64e9081b3c3aa4.

Reason for revert:
Some Cr50 chips with old firmware version (x.y.22) don't support
long pulse interrupt command, requiring dynamic GPIO PM to be disabled
to intercept short pulse interrupt.

Due to this coreboot needs to expose SGPM, RGPM and EGPM ACPI methods
to support power gating of GPIO communities from the kernel when dynamic
GPIO PM is disabled.

BUG=b:204832081
BRANCH=None
Test= S0ix works with dynamic PM disabled.
