[media] feature-removal: update V4L1 removal status 

While the V4L1 compatibility module has been removed, we still have
two V4L1 drivers that prevent full V4L1 removal.

Those drivers have been moved to staging and will be removed in 2.6.39,
together with the last V4L1 support.

What: Video4Linux API 1 ioctls and from Video devices.
When: kernel 2.6.38
When: kernel 2.6.39
Files: include/linux/videodev.h
Check: include/linux/videodev.h
Why: V4L1 AP1 was replaced by V4L2 API during migration from 2.4 to 2.6
series. The old API have lots of drawbacks and don't provide enough
means to work with all video and audio standards. The newer API is
already available on the main drivers and should be used instead.
Newer drivers should use v4l_compat_translate_ioctl function to handle
old calls, replacing to newer ones.
Decoder iocts are using internally to allow video drivers to
communicate with video decoders. This should also be improved to allow
V4L2 calls being translated into compatible internal ioctls.
Compatibility ioctls will be provided, for a while, via
v4l1-compat module.
The userspace libv4l1 library can convert V4L1 calls to V4L2. This
replaces the kernel V4L1 compatibility module which was removed in
2.6.38. The last V4L1 drivers will either be converted to V4L2 or
removed for 2.6.39 at which point the V4L1 API will cease to exist.

Why: There are some drivers still using V4L1 API, despite all efforts we've done
to migrate. Those drivers are for obsolete hardware that the old maintainer
didn't care (or not have the hardware anymore), and that no other developer
could find any hardware to buy. They probably have no practical usage today,
and people with such old hardware could probably keep using an older version
of the kernel. Those drivers will be moved to staging on 2.6.37 and, if nobody
care enough to port and test them with V4L2 API, they'll be removed on 2.6.38.
