ArmVirtualizationPkg: clone BasePciExpressLib, cache PCIe config base The BarExisted() function in "MdeModulePkg/Bus/Pci/PciBusDxe/PciEnumeratorSupport.c" raises the TPL to TPL_HIGH_LEVEL before accessing PCI config space. The PciExpressLib instance under "MdePkg/Library/BasePciExpressLib" -- serving the PCI config space access -- calls PcdGet64(PcdPciExpressBaseAddress) in turn, for each such call. The PcdGet64() function, when issued at TPL_HIGH_LEVEL, triggers an ASSERT(). PcdGet64() is based on a protocol in this UEFI phase, and protocol handler services are not allowed above TPL_NOTIFY (see Table 23 "TPL Restrictions" in the UEFI spec). Clone the library, and in a new constructor, cache the PCD in a global variable.
