MLK-21107-2: ASoC: Drop msg if msg queue is full
We designed length of msg queue to be 0x18, which is too
small if the period size = 512bytes, sometimes the queue
will be full, which cause the msg is replaced by new one.
which is not acceptable.
So we need to enlarge the length of msg queue and add
protection when msg queue is full, if the msg queue is full
with the cmd (START, STOP, PAUSE...), driver will return
error, with the cmd (I2S_TX_POINTER, I2S_TX_PERIOD_DONE)
driver will drop the cmd.
