Subject: [PATCH v5 7/8] remoteproc: Allow overriding only sanity_check

Now that rproc_elf_sanity_check can be used by external drivers, allow
to only overwrite the sanity_check member of rproc_ops. This will allow
drivers to handle elf32 and elf64 by overwriting sanity_check with
rproc_elf_sanity_check function.
