This patch changes the device configuration to support capture
of V4L2_PIX_FMT_GREY video. The 'write_format' field of the format
description should be planar.
Also the array 'pixm->plane_fmt' that describes the planes should
be memset to 0 before filling it since the the cb, cr planes should
be 0.
