FROMLIST: scsi: ufs: Add HCM support to rsp_upiu
In device control mode, the device may recommend the host to either activate or inactivate a region, and the host should follow. Meaning those are not actually recommendations, but more of instructions. On the contrary, in host control mode, the recommendation protocol is slightly changed: a) The device may only recommend the host to update a subregion of an already-active region. And, b) The device may *not* recommend to inactivate a region. Furthermore, in host control mode, the host may choose not to follow any of the device's recommendations. However, in case of a recommendation to update an active and clean subregion, it is better to follow those recommendation because otherwise the host has no other way to know that some internal relocation took place.
