Firmware R2101 has missing v4l controls for oCam-1CGN-U-T #24

This commit causes white_balance_red_component and white_balance_blue_component to disappear from v4l control options of the camera oCam-1CGN-U-T. I rolled back the firmware to R2006 and these control options came back. (Note: with windows viewer, white balance can still be changed with R2101 firmware for some reason)

(redacted)@(redacted):~$ uname -a

With R2101 firmware, v4l2 options output:

With R2006 firmware, v4l2 options output:
