media: atomisp: ov2680: Stop using half pixelclock for binned modes

Browse source

[ Upstream commit 7d45a43225 ]

Stop using half pixelclock for binned modes this fixes:
1. The exposure being twice as high for binned mods (due to the half clk)
2. The framerate being 15 fps instead of 30 fps

The original code with fixed per mode register lists did use half pixel
clk, but this should be combined with using half for the VTS value too.

Using half VTS fixes the framerate issue, but this has the undesired
side-effect of change the exposure ctrl range (half the range, double
the amount of exposure per step).
