[PATCH v2] gst-plugins-good: v4l2src: Make Leapoard Imaging VGA Camera work out of the box

Format enumeration in Gstreamer expects drivers to implement VIDIOC_ENUM_FMT and if not, it calls
VIDIOC_TRY_FMT on a set of "emulated formats" which could be unsupported resulting in failure of
the format negotiation stage [1]

We add UYVY to the set of formats making the mt9v113 sensor in this camera board and other sensors
that don't support the emulated formats work out-of-the box without needing a caps filter element

Upstream-Status: Inappropriate
- This patch is a quick work around for a limitation of the ISP driver's lack of support of the
VIDIOC_ENUM_FMT IOCTL [2]
