ANDROID: scsi: ufs: Support Multi-Circular Queue

To improve performance, UFS4.0 HCI introduce the option to use
Multi-Circular Queue. With the availability of this option,
HCI can operate in legacy queue mode and be backward compatible
with older UFS device. Or the HCI can enable MCQ for improve
performance with UFS4.0 device or later.

Since MCQ specification is just finalized recently, some vendors
have non-standard design at this time due to following the earlier
draft versions.

This patch provides ways to support such non-standard MCQ
implementation by vendors by using add-on hooks in existed UFS
driver. Vendors can implement their own "draft design" in vendor
drivers, and meanwhile not breaking the legacy non-MCQ path.
