----------------------------------------------------------------
EFI fixes for v5.14-rc2:

A batch of fixes for the arm64 stub image loader:
- fix a logic bug that can make the random page allocator fail
spuriously
- force reallocation of the Image when it overlaps with firmware
reserved memory regions
- fix an oversight that defeated on optimization introduced earlier
where images loaded at a suitable offset are never moved if booting
without randomization
- complain about images that were not loaded at the right offset by the
firmware image loader.
