feat(stm32mp1): add FWU with boot from NOR-SPI

Refactor the SDCARD/EMMC FWU, to add the NOR-SPI use case.
SPI-NOR FWU won't use a real partition uuid to find the correct FIP,
but the UUID from metadata will correspond with a hardcoded offset in
the NOR.
While at it change some __unused keywords to __maybe_unused to ease
checkpatch.pl analysis.
