You mussed what I asked for in terms of adding a new flag, (please work on top
of Andre's patches as those likely will be merged first, and also have kdocs
for the flags) and then a new firmware API to wrap the above into a function
which would only do something if the driver *asked* for it on their firmware
API call.  Ie, please add a new firmware_request_efi_fw(). Also if you see the
work I've done to remove the ifdefs over fallback mechanism you'll see it helps
split code and make it easier to read. We should strive to not add any more
ifdefery and instead make tehis code read easily.
