[media] V4L: add CCF support to the v4l2_clk API
V4L2 clocks, e.g. used by camera sensors for their master clock, do not have to be supplied by a different V4L2 driver, they can also be supplied by an independent source. In this case the standart kernel clock API should be used to handle such clocks. This patch adds support for such cases.
