Right, in the imx219, on exit from s_power(), the clock and data lanes
must be placed in the LP-11 state. This has been done in the ov5640 and
tc358743 subdevs.

If we want to bring in the patch that adds a .prepare_stream() op,
the csi-2 bus would need to be placed in LP-11 in that op instead.

Philipp, should I go ahead and add your .prepare_stream() patch?
