This helper is used by the EFI driver and we would like to use that on ARM. Move the helper function into its own file, separate from PCI ROMs, which are an x86 thing. Add a forward declaration for struct udevice so that the header can be included directly. Signed-off-by: Simon Glass <sjg@chromium.org>
