Thanks for pointing it.

Will fix in v3. On MIPI D-PHY, lane 0 is the clock lane, so data lanes
must start from 1 as per video-interfaces.yaml binding spec.

Agreed, will move it to the .dtso in v3.

This also eliminates the identical cam1_reset_default block duplicated across 
CQM and CQS board files.

Will incorporate this for the IQS dtso file.
