media: dvb: move most compat_ioctl handling into drivers
Most DVB audio and video ioctl commands are completely compatible, and are implemented by just two drivers: ttpci and ivtv. In both cases, we can use the same ioctl handler for both native and compat ioctl handling, and remove the entries from the global lookup table. In case of ttpci, this directly hooks into the file_operations structure, and for ivtv, we have to set the compat_ioctl32 method in v4l2_file_operations. For all I can tell, setting it to video_ioctl2 will still do the right thing for all commands. Note that for the VIDEO_STILLPICTURE and VIDEO_GET_EVENT commands, a translation handler in fs/compat_ioctl.c is still used. This works because the command numbers are different on 32-bit systems.
