ASoC: fsl_xcvr: get channel status data when PHY is not exists

Browse Source 
commit ca592e2065 upstream.

There is no PHY for the XCVR module on i.MX93, the channel status needs
to be obtained from FSL_XCVR_RX_CS_DATA_* registers. And channel status
acknowledge (CSA) bit should be set once channel status is processed.
