Make BaseCachingPciExpressLib depend on PciPcdProducerLib, so that we
have a chance to populate PcdPciExpressBaseAddress based on the contents
of the device tree. 

Also update the platforms under ArmVirtPkg that support PCI to use this
special MAX_UINT64 as the build time default for PcdPciExpressBaseAddress,
and to specify a suitable resolution for PciPcdProducerLib.

Just a suggestion: s/MAX_UINT64/MAX_UINT64 value/?
