ENGR00220172 ESAI ASRC: put all asrc pair release operation to shutdown()
When use ASRC for ESAI P2P playback, ESAI driver would release ASRC pair
resource immediately after ASRC function's error return.It may
introduce risk that in ESAI machine driver's shutdown(), ASRC resource
release operation may be double called. In this case, system hang
happens due to ASRC register's operation with no clock.
In this patch, let all ASRC resource release operation in ESAI machine
driver's shutdown().
