ASoC: fsl_xcvr: get channel status data with firmware exists 



For the XCVR module on i.MX95, even though it only supports SPDIF, the
channel status needs to be obtained from RAM space, which is processed
by firmware. Firmware is necessary to trigger the FSL_XCVR_IRQ_NEW_CS
interrupt.

This change also applies for the SPDIF & ARC function on i.MX8MP which
has the firmware.
