media: ov6650: Fix incorrect use of JPEG colorspace
[ Upstream commit 12500731895ef09afc5b66b86b76c0884fb9c7bf ]
Since its initial submission, the driver selects V4L2_COLORSPACE_JPEG
for supported formats other than V4L2_MBUS_FMT_SBGGR8_1X8. According
to v4l2-compliance test program, V4L2_COLORSPACE_JPEG applies
exclusively to V4L2_PIX_FMT_JPEG. Since the sensor does not support
JPEG format, fix it to always select V4L2_COLORSPACE_SRGB.
