mmc: cmdq_hci: disable CDR in CQ mode

The CDR is supposed to be enabled only for read commands but
since there is no way it can be done in CQ, disable it completely
in CQ mode.

The CDR gets enabled by default whenever tuning is done in legacy
mode. Hence, make sure to disable it when CQ is enabled or when
CQ is unhalted.

Also note that CDR plays a role only in these bus speed modes -
HS200 and HS400 with enhanced strobe disabled.
