soc/intel/alderlake: Correct GPE DWx assignment as per EDS
List of changes:
1. Update GPIO Group to GPE DWx assignment encoding as per MISCCFG
register per GPIO Community.
2. PMC_GPP_* macros are also updated as per GPIO_CFG register
in PMC space.
BUG=b:183464235
TEST=Able to fix the TPM IRQ issue on SM.
