From: Ezequiel Garcia <ezequiel@xxxxxxxxxxxxx>
Introduce support for the Request API. Although the JPEG encoder
does not mandate using the Request API, it's perfectly possible to
use it, if the application wants to.

Changes from v2:
* Drop unrelated mdev.bus_info changes.
* Remove the get_ref and get_ctrl helpers as they are not used yet.
