This adds an implementation of NorFlashPlatformLib that exposes the
two 64 MB NOR flash banks that are provided by QEMU's mach-virt
emulation both in 32-bit and 64-bit mode.

Retained the 'Reviewed-by: Laszlo Ersek <lersek@redhat.com>' as the only change
is removing a duplicated (so identical) typedef of NOR_FLASH_DESCRIPTION.
