Since checks are present in the remoteproc elf loader before calling
da_to_va, loading a elf64 will work on 32bits flavors of kernel.
Indeed, if a segment size is larger than what size_t can hold, the
loader will return an error so the functionality is equivalent to
what exists today.

Do you still need the capability to override the sanity_check? As I
understand, you introduced this to allow platform drivers to use the
appropriate elf32 or elf64 one during the ELF64 loader support series.
