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.
