The Camera Subsystem clock provider have a bunch of generic properties
that are needed in a device tree. Add a YAML schemas for those.
Add clock ids for Camera clocks which are required to bring the camera
subsystem out of reset.

Why do we need board XO

And also the gate on XO in GCC? Presumably only the one in GCC should be
going to the camera clock controller?
