soc/intel/common/block/p2sb: Refactor P2SB to add comprehend future SoC
This patch refactors the current P2SB common code driver to accommodate
the future SoC platform with provision of more than one P2SB IP in
disaggregated die architecture.
IA SoC has only one P2SB in PCH die between SKL to ADL. Starting with
MTL, one more P2SB IP resides in IOE die along with SoC die. (PCH die is
renamed as SoC in MTL.)
P2SB library (p2sblib.c) is common between PCH/SoC and IOE, and p2sb.c
is added only for PCH/SoC P2SB.
BUG=b:224325352
TEST=Able to build and boot brya.
