[PATCH v2 0/2] hw/ufs: Add support MCQ

[Minwoo Im]

UFSHCI 4.0 spec introduced MCQ(Multi-Circular Queue) to support multiple
command queues for UFS controller.  To test ufs-mcq path of kernel, MCQ
emulated device would be a good choice to go with.

The first patch added newly introduced fields in UFSHCI 4.0 to support
MCQ.  The other one made the actual changes for MCQ.

v2:
  It fixed printing error event trace even in normal shutdown cases for
SQ/CQ tear-down by checking whether each SQ/CQ is valid or not.  The
default value of mcq-maxq was updated to 2 from 1 to prevent the kernel
from allocating a single queue as a poll_queue by default and to ensure
that io_queues exist to handle device commands.

Please review.

Thanks,
