Add ADP-P PCH device ID and assign as ADL PCH if found. Previously we would assign the DDC pin map based on the PCH, but it can also change based on the CPU. From Bspec 20124: "The physical port to pin pair mapping are defined in the Bspec per PCH. Mapping can further change based on CPU Si used as CPU and PCH can be mixed and matched".
