- Do not clear V4L2_FL_USES_V4L2_FH flag because this
flag indicates that file->private_data points to
&struct v4l2_fh.
- Initialize v4l2 ctrl handler with driver ctrl handler.
- Add ctrl ops for g_volatile_ctrl to return updated
value of volatile ctrls from driver.
Fixes: v4l2-compliance:
testPrio (VIDIOC_G/S_PRIORITY).
testQueryControls (VIDIOC_QUERYCTRL).
