[PATCH v5 3/7] MdeModulePkg/PciBusDxe: dispatch option ROMs for foreign architectures

["Ard Biesheuvel" <ard.biesheuvel@linaro.org>]

Delete the explicit machine type check for option ROM images, and instead,
rely on the LoadImage() boot service to decide whether an option ROM can
be dispatched or not. This permits platforms to ship with emulators to
execute option ROMs that are not native to the processor architecture.
