Use standard V4L2 control to get pixel clock rate from a sensor
linked in the media controller pipeline. Then calculate clock
rates on CSIPHY, CSID and VFE to use the lowest possible.
If the currnet pixel clock rate of the sensor cannot be read then
use the highest possible. This case covers also the CSID test
generator usage.
If VFE is already powered on by another pipeline, check that the
current VFE clock rate is high enough for the new pipeline.
If not return busy error code as VFE clock rate cannot be changed
while VFE is running.

These files control the CSIPHY modules which are responsible for the
physical layer of the CSI2 receivers.
