Avoid swr fifo overflow by checking no. of outstanding
commands in fifo and comparing with fifo depth before
every read/write. If no. of commands is equal to fifo
depth then give some delay and retry. If no of outstanding
commands are still equal to fifo depth then flush fifo
and try writing/reading from fifo again.

Audio core vote enables soundwire master and establishes
soundwire link without which soundwire master will not power up.
This change votes for audio core during soundwire runtime
resume and unvotes during soundwire runtime suspend.

Headset insertion/removal is not detected sometime due to
fifo read failure due to swr underflow. This is because if
headset sva is enabled, during clk switch swr force stop
happens and if mbhc has already taken pm vote for 3sec
further mbhc reads/writes will fail. If swr is in clk switch
mode then call swrm runtime_resume during reads/writes
to resolve issue.

Headset is not detected if devnum 0 gets detached at bootup.
This is because on detach being called hw will mask interrupt
at slave side but will not unmask it afterwards.
Also device 0 is used only for discovery purpose and
interrupt shouldnt be masked if it detaches.
