[RFCv1 PATCH 14/16] hexium-gemini: remove B&W control, fix input table.



From: Hans Verkuil <hans.verkuil@xxxxxxxxx>

The B&W control never worked, and you get the same effect by setting saturation to the
lowest value. So it has been removed. Also fixed some incorrect entries in the input
table. This driver now passes v4l2-compliance.
