OvmfPkg: IndustryStandard/Q35MchIch9.h: add PCIEXBAR macros 

Section 5.1.16 ("PCIEXBAR -- PCI Express Register Range Base Address") in
Intel document #316966-002 (already referenced near the top of this header
file) describes the Q35 DRAM Controller register that configures the
memory-mapped PCI config space (also known as MMCONFIG, and ECAM /
Enhanced Configuration Access Method).

In this patch we add the macros we'll need later. We'll only support the
256 MB memory-mapped config space -- enough for buses [0, 255].
