For the ov7670 camera to return images at the requested frame rate,
it needs to make calculations based on the clock speed, which is
a completely external factor (depends on the wiring of the system).
On the XO-1.5, which is the only known via-camera user, the camera
is clocked at 90MHz.
Pass this information to the ov7670 driver, to fix an issue where
a framerate of 3x the requested amount was being provided.

This flag is for legacy drivers only and will go away in the future.
A note regarding commit 5126f2590b
(v4l2-dev: add flag to have the core lock all file operations):
That commit message suggests that by not taking the core lock for fops
other than unlocked_ioctl all problems relating to AB-BA locking and
mm->mmap_sem are solved. This is not the case.
More work needs to be done by moving the core lock further down into
video_ioctl2. It should only be taken after the copy_from/to_user calls
are done.

The querycap ioctl returned an incorrect version number and incorrect
capabilities (mixing up vbi and video caps).
The reason for that was that video nodes could do vbi activities: that
should be separated between the vbi and video nodes.
There were also a few minor problems with dbg_g/s_register that have
been resolved. The mxb/saa7146 driver now passes the v4l2_compliance tests.
