hw/ufs: Add support MCQ of UFSHCI 4.0

This patch adds support for MCQ defined in UFSHCI 4.0.  This patch
utilized the legacy I/O codes as much as possible to support MCQ.

register statically with no spare space among four registers (48B):

	UfsMcqSqReg, UfsMcqSqIntReg, UfsMcqCqReg, UfsMcqCqIntReg

The maxinum number of queue is 32 as per spec, and the default
MAC(Multiple Active Commands) are 32 in the device.

Example:
	-device ufs,serial=foo,id=ufs0,mcq=true,mcq-maxq=8
