Enhance function macro EFI_PEI_PCI_CFG_ADDRESS defined in MdePkg/Include/Ppi/PciCfg2.h to generate the correct Address for PI PciCfg PPI when bus number is larger than 127 and reg is less than 256. And Enhance function macro EFI_PEI_PCI_CFG_ADDRESS to handle that reg is larger than and equal to 256.
