mmc: queue: initialization of command queue

Command Queueing (CQ) feature is introduced to eMMC
standard in revision 5.1. CQ includes new commands
for issuing tasks to the device, for ordering the
execution of previously issued tasks and for
additional task management functions.

The idea is to keep the legacy and CQ code as discrete
as possible. Hence, a separate queue is created for CQ.
The issuing path is non-blocking since several requests
(max. 32) can be queued at a time.
