em28xx: add raw VBI support for NTSC
From: Devin Heitmueller <dheitmueller@kernellabs.com>
Add support for raw VBI capture for the em28xx bridge, currently only for
NTSC. Support for PAL capture to follow shortly (including the removal of
numerous hard-coded NTSC-specific sizes for capture buffers, etc).
Note that the code currently changes the default current norm from PAL to
NTSC (so that zvbi-ntsc-cc works properly). The default norm really should
be moved into a board-level parameter.
This work was sponsored by EyeMagnet Limited.
Priority: normal
