scsi: ufs: pci: Add support MCQ for QEMU-based UFS

Recently, ufs-mcq feature has been introduced to QEMU hw/ufs device [1].
This patch adds MCQ support for upstream QEMU UFS PCI controller.  This
patch provides mandatory vops callbacks to make UFS controller work
properly on MCQ mode.  Operation and Runtime Config register stride is
fixed to 48bytes which is implemented by qemu.
