I plan to replace it with lib/bitmap.c bitmap_* based allocator

IMHO allocate_resource and friends a bit too heavy here, but good to
know
that such allocator also exists.
Not sure I'd class allocate_resource as heavyweight but providing it's
using something that already exists rather than inventing yet another
allocator.
genalloc is already in the kernel and is used in a few places, so we
either let everyone use it as they see fit or we deprecate the library.
If we don't deprecate it I see no reason why CMA should not use it.
