msm: camera: Enable front camera or cam1 for 8974

Add support for CSID cores to enable CSID0 clocks by default since
CSID1, CSID2 and CSID3 cores requires CSID0 clocks. Add support to
extract phy-sel value from device tree node and pass it to CSID core.
With phy-sel value in device tree node, sensor can choose CSIPHY core
and CSID core to use for streaming. Reading buffer if probe fails causes
CCI to enter into bad state and future I2C call fails. Avoid CCI from
reading buffer if probe fails.
