This series enables jack detection for HDMI audio on vc4 devices.  This
means that userspace audio applications can detect when HDMI devices are
connected or disconnected, for example to play/pause or switch to
another audio device.

Changes in V3:
- Update comment on drm_atomic_helper_connector_hdmi_hotplug() to
  clarify that it must be called for disconnets too

Changes in V2:
- split initial patch into fix and jack detection feature as
  suggested by Dmitry
