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.

This short-circuit path in sysret_signal looks wrong to me.
AFAICT, in practice the branch is never taken--and if it were,
it would go wrong. To wit, try loading a module whose init
function does set_thread_flag(TIF_IRET), and see insmod crash
(presumably with a wrong user stack pointer).
This is because the FIXUP_TOP_OF_STACK work hasn't been done yet
when we jump around the call to ptregscall_common and get to
int_with_check--where it expects the user RSP,SS,CS and EFLAGS to
have been stored by FIXUP_TOP_OF_STACK.
I don't think it's normally possible to get to sysret_signal with no
_TIF_DO_NOTIFY_MASK bits set anyway, so these two instructions are
already superfluous. If it ever did happen, it is harmless to call
do_notify_resume with nothing for it to do.

videodev.c became top-heavy so all the ioctl processing has been split off
into v4l2-ioctl.c. This means videodev.c is back to its original purpose:
creating and registering v4l devices.
Since videodev.c and v4l2-ioctl.c should still remain one module (as least
for now) I also had to rename videodev.c to v4l2-dev.c to prevent a
circular dependency when building a videodev.ko module. This is not a bad
thing, since the source and header now have the same name. And the v4l2-
prefix is useful to see which sources are generic v4l2 support code.
