ASoC: msm: qdsp6v2: Add a new waitqueue state for mem map/unmap

All of the commands being sent to the DSP are using cmd_state flag
which can be overwritten when several commands are sent at the same
time. This results in Memory map command timing out. The change will
separate the memory flag from flags for other commands so that they
do not overwrite each other.
