This patch adds metadata support in vivid driver.
Metadata capture supports UVCH format V4L2_META_FMT_UVC as it is widely used in webcams.
https://hverkuil.home.xs4all.nl/spec/uapi/v4l/pixfmt-meta-uvc.html
For Metadata output a new format V4L2_META_FMT_VIVID is added,
which is used to set brightness, contrast, sturation and hue.

Regards,
Vandana.
