scsi: ufs: Add program_key() variant op
On Snapdragon SoCs, the Linux kernel isn't permitted to directly access the
standard UFS crypto configuration registers. Instead, programming and
evicting keys must be done through vendor-specific SMC calls.
To support this hardware, add a ->program_key() method to 'struct
ufs_hba_variant_ops'. This allows overriding the UFS standard key
programming / eviction procedure.
