media: ov9640: Use the generic clock framework
Commit 63839882c597 ("media: mach-pxa: palmz72/pcm990: remove soc_camera dependencies")
removed the last in-tree user of this sensor. New users
will be required to use the generic clock framework,
so it's possible to convert the driver to use it.
Convert the driver to use the CCF, and drop the legacy
v4l2-clk API.
