[media] fsl_viu: add VIDIOC_QUERYSTD and VIDIOC_G_STD support
VIDIOC_QUERYSTD and VIDIOC_G_STD ioctls are currently not supported in the FSL VIU driver. The decoder subdevice driver saa7115 extended by previous patch supports QUERYSTD for saa711x, so we add the appropriate ioctls to the VIU driver to be able to determine the video input's standard.
