V4L/DVB (8816): gspca: Set disabled ctrls and fix a register pb with ovxxxx in sonixb.

- set some controls as disabled instead of copying the device descr.
- in the ov6650 / 7650 exposure code clamp reg 11 before (instead of after)
  using it to calculate reg 10.
- disable brightness (instead of ignoring it) for the TAS5110.
