Block crypto allows storage controllers like UFS to
register ops to generate, prepare and import wrapped
keys in the kernel.
Wrapped keys in most cases will have vendor specific
implementations, which means these ops would need to have
corresponding UFS variant ops.
This change adds hooks in UFS core to support these variant
ops and tie them to the blk crypto ops.
