NonDiscoverablePciDeviceDxe currently #defines the module-internal PCI_MAX_BARS macro, with value 6 (and type "int"). Remove this private macro definition, and adopt PCI_MAX_BAR from "MdePkg/Include/IndustryStandard/Pci22.h". Both the value and the type remain unchanged (the standard PCI_MAX_BAR macro expands to 0x0006). "NonDiscoverablePciDeviceIo.h" gets the definition of PCI_MAX_BAR via its existent #include <IndustryStandard/Pci.h> directive. Build-tested only.
