This implements a library FdtPciPcdProducerLib which is intended to be incorporated into modules that consume the PCI related dynamic PCDs PcdPciExpressBaseAddress and PcdPciDisableBusEnumeration, either via NULL library class resolution or via a direct dependency (for other libraries or modules in ArmVirtPkg). This allows us to make them depend on the FDT client protocol, and populate these PCDs based on the presence and the contents of a 'pci-host-ecam-generic' DT node. This also overloads the meaning of PcdPciExpressBaseAddress, which we will set to MAX_UINT64 to signify that the actual values of these two PCDs have not been assigned yet.
