scsi: ufs: core: mcq: Configure operation and runtime interface
Runtime and operation registers are defined per Submission and Completion
queue. The location of these registers is not defined in the spec; meaning
the offsets and stride may vary for different HC vendors. Establish the
stride, base address, and doorbell address offsets from vendor host driver
and program it.
