[v2,1/2] media: i2c: st-vgxy61: Add V4L2_SUBDEV_FL_HAS_EVENTS and subscribe hooks

Commit Message

Alain Volmat Nov. 27, 2023, 1:51 p.m. UTC

Any V4L2 subdevice that implements controls and declares
V4L2_SUBDEV_FL_HAS_DEVNODE should also declare V4L2_SUBDEV_FL_HAS_EVENTS
and implement subscribe_event and unsubscribe_event hooks.

With that done, v4l2-compliance testing is now ok.
