[0/4] media: allegro: move driver out of staging

Hello,

With the V4L2 stateful encoder spec being finished, the Allegro encoder driver
is ready to be moved from staging to mainline.

While not directly related, I used the opportunity to convert the dt-binding
to YAML, to remove the custom draining state handling from the driver and to
rename a badly named field in the MCU messages.
