Commit 63839882c5 ("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.

This patch removes the dependency on an obsoleted soc_camera from ov9640
driver and changes the code to be a standalone v4l2 async subdevice.
It also adds GPIO allocations for power and reset signals (as they are not
handled by soc_camera now).
The values for waiting on GPIOs (reset and power) settling down were taken
from the datasheet (> 1 ms after HW/SW reset). The upper limit was chosen
as an arbitrary value. Also one occurrence of mdelay() was changed to
msleep(). The delays were successfully tested on a real hardware.
The patch makes ov9640 sensor again compatible with the pxa_camera driver.

Initial part of ov9640 transition from soc_camera subsystem to a standalone
v4l2 subdevice. The soc_camera version seems to be used only in Palm Zire72
and in (the future) HTC Magician. On these two devices the support is
broken as pxa_camera driver doesn't use soc_camera anymore. The other
mentions from git grep are "TODOs" (in board-osk.c) or chip names for
unsupported sensors on HW which doesn't use soc_camera at all (irelevant).
Copy the driver files from soc_camera and mark the original ones in the
Kconfig description as obsoleted.
Add config option VIDEO_OV9640 to the build files in drivers/media/i2c.
