V4L/DVB (4475): Fix most Compat32 stuff on V4L2
Tested on x64 with a bttv board. Most Get ioctls are fixed. The only
non-completely working one is VIDIOCGAUDIO. All other IOR ioctls give the
same results on x86_64 and i386 architectures.
Thanks to Alastair Poole <netstar@gatheringofgray.com> for part of this
patch and tests on ppc64.
