Erik Andr?n bd99ffbd2a V4L/DVB (11421): gspca - m5602-ov9650: Synthesize modesetting. 
Previously all resolution setting was done with precalculated tables.
When the image is vflipped we need to adjust the alignment which would
require another table. Now we can adjust the parameters on the fly instead.
