Leave it to the V4L2 core to set the description. In fact, that was already the case for a long time since v4l_fill_fmtdesc() overwrites the description. So remove all description strings from the driver. uvc_ioctl_enum_fmt() was also cleaned up a bit since zeroed the v4l2_fmtdesc struct, when all fields after 'type' are already zeroed by the V4L2 core.
