[PATCH] MdeModulePkg/NonDiscoverablePciDeviceDxe: use standard PCI_MAX_BAR macro

["Laszlo Ersek" <lersek@redhat.com>]

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.
