Setting the value of the V4L2_CID_VFLIP control is currently ignored.
Because V4L2_CID_HFLIP and V4L2_CID_VFLIP are independently controlled
in s_ctrl() but these controls belong to the same cluster and the first
control is V4L2_CID_HFLIP.
Fix it by not clustering these controls. Also correct erroneous updating
register bit for vertical flip.
