[PATCH] media: controls: Add VP8 stateless type initialization

[PATCH] media: controls: Add VP8 stateless type initialization

[Ezequiel Garcia]

The VP8_FRAME_HEADER control type is validated, so it
needs a corresponding initialization to produce default
legal values.

For now, only add the minimum required initialization
to satisfy current validation.
