ASoC: fsl_mqs: Distinguish different modules by system manager indices

On i.MX94, the MQS2 also needs to be configured by SCMI interface, add
sm_index variable in struct fsl_mqs_soc_data to distinguish the MQS1 and
MQS2 on this platform.

Add the system manager indices for i.MX94 in the header file.
