soc: swr-mstr: Fix headset detection during sva clk switch

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.
