This series fixes two gaps that prevent a UFSHCI 4.1 host from bringing the
emulated device up and using it over MCQ.
Patch 1 adds minimal DME_GET/SET handling for the PA layer attributes that a
host reads and writes when negotiating the link power mode after
DME_LINK_STARTUP. Previously every DME command other than LINK_STARTUP and
HIBER_{ENTER,EXIT} returned FAILURE, so the power-mode change could not
complete.
Patch 2 populates cqe.task_tag (and lun) in the MCQ completion path. The
device reports version 4.1, for which the request tag is conveyed in the CQE
task_tag field instead of being derived from the command descriptor base
address, so completions were all decoded as tag 0.
