soc/intel/common/block: Add Intel common PCR support
IOSF_SB message space is used to access registers mapped on IOSF-SB. These registers include uncore CRs (configuration registers) and chipset specific registers. The Private Configuration Register (PCR) space is accessed on IOSF-SB using destination ID also known as Port ID. Access to IOSF-SB by the Host or System Agent is possible over PSF via the Primary to Sideband Bridge (P2SB). P2SB will forward properly formatted register access requests as CRRd and CRWr request via IOSF-SB.
