[PATCH 04/13] media: bttv: move vid fmt/width/height out of fh

[Deborah Brouwer <deborah.brouwer@xxxxxxxxxxxxx>]

Instead of storing video format, width and height separately in each file
handle, move these fields to the main struct bttv. Use them wherever
possible in preparation for vb2 conversion which stops using separate bttv
file handles.
