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

Browse Source 
[ Upstream commit ca592e2065 ]

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.
