All ioctl callbacks are now stored in a new v4l2_ioctl_ops struct. Drivers fill in
a const struct v4l2_ioctl_ops and video_device just contains a const pointer to it.

This ensures a clean separation between the const ops struct and the non-const
video_device struct.

Andoni Zubimendi has been doing some testing with his sn9c103 cam with
ov7630 sensor, and with this patch the exposure setting and autoexposure now
work.

This patch also removes some special cases in the shared ov6650 / ov7630 code
which now are handled the same for both sensors and it adds a new special case
which stops us from changing the hsync / vsync polarity settings from their
default on the ov7630 (which we were doing as a side-effect of using the ov6650
exposure code for the ov7630).

Last this patch removes the superficial difference between the OV7630 and
OV7630_3 sensors.

The functions in a header should not belong to another module. The prio functions
belong to v4l2-common.c, so move them to v4l2-common.h.

The ioctl functions belong to v4l2-ioctl.c, so create a new v4l2-ioctl.h header
and move those functions to it.

The sn9c102 driver claims to support usb-ID 0x0c45:0x6011, which is
a sn9c102 with ov6650 sensor, but the sn9c102 driver does not support the
ov6650 sensor (tested). Also the sn9c102 driver claims to support usb-ID
0x0c45:0x603f, which is a sn9c102 with CISVF10 sensor, but the sn9c102
driver does not support the CISVF10 sensor (not tested).
