boards: cxd56xx: Fix bugs about ON/OFF control of AWB and AE

Browse Source 
Fix the following three bugs about ON/OFF control of auto white balance and auto
exposure:

 - The returned value of VIDIOC_G_CTRL with id = V4L2_CID_AUTO_WHITE_BALANCE is
different from V4L2 specification.
 - Auto exposure is locked if auto white balance lock is requested.
 - Auto exposure and auto white balance are locked if auto exposure lock is
requested.
