ANDROID: scsi: ufs: add vendor hook to override key reprogramming

Some hardware has a way to restore all keyslots at once that is
significantly faster than restoring each keyslot individually, as is
done by blk_ksm_reprogram_all_keys().  Add a hook
"android_rvh_ufs_reprogram_all_keys" that allows overriding the
restoration of all keyslots after UFS reset.  This may sleep, so this
must be a "restricted" Android vendor hook rather than a regular one.

Note that currently this functionality can't be upstreamed, as support
for the hardware that needs it would need to be upstreamed first.
