LF-215: ASoC: fsl_rpmsg_i2s: Enable WQ_FREEZABLE for workqueue
In the end of playback, when the suspend happen, there will be error
in m4 side.
RTM_SaiSdmaAdapter_SetParam: Tx in wrong state 2!
SRTM_SaiSdmaAdapter_SetBuf: Tx in wrong state 2!
SRTM_SaiSdmaAdapter_Start: Tx in wrong state 2!
The reason is that the I2S_TX_TERMINATE happen in the middle of
I2S_TX_SUSPEND and I2S_TX_RESUME, this sequence is not allowed.
So we make the rpmsg message workqueue enter freeze in suspend
to avoid such issue. that the command sequence will be
I2S_TX_SUSPEND->I2S_TX_RESUME->I2S_TX_TERMINATE
