soc/intel/cmn/sa: Add APIs into System Agent (SA) common code
This commit streamlines code and strengthens common code robustness by moving the following SoC-layer functions to the common layer:
- sa_get_mmcfg_size: Retrieves the MMIO (Memory-Mapped I/O) configuration space size by reading offset 0x60 of the PCI Host Bridge (D0:F0). - sa_get_dsm_size: Calculates the size of the DSM (Device Stolen Memory) by reading offset 0x50 of the PCI Host Bridge (D0:F0) to determine pre-allocated memory for the IGD (Integrated Graphics Device). - sa_get_gsm_size: Calculates the size of the GSM (Graphics Stolen Memory) by reading offset 0x52 of the PCI Host Bridge (D0:F0). - sa_get_dpr_size: Determines the size of the DMA Protection Range (DPR) by reading offset 0x5C of the PCI Host Bridge (D0:F0).
