soc/intel/common/acpi: Create helper APIs for common P2SB access
This patch creates a helper library to migrate all the common P2SB access routines. The PCH P2SB ACPI implementation will now rely on the common library to perform PCR read/write operations. This will make the code more modular and easier to maintain. The helper library provides a single interface for accessing P2SB registers. This makes it easier to port the code to different platforms, for example: adding support for PS2B belongs to the IOE die for Meteor Lake SoC generation.
