This series include misc cleanup of the meson-dw-hdmi driver, changes to
use the bridge CEC notifier op and to use the dw-hdmi delayed work for
HPD event handling.

Patch 1 ensure connector status is based on HPD bit
Patch 2 protect from a possible NULL pointer dereference during bind()
Patch 4 reduce number of hotplug uevents and hpd_notify() calls
Patch 6 changes to use bridge connector CEC notifier
Patch 3,5,7-10 cleanup code for consistency
Patch 11-12 changes to use dw-hdmi HPD delayed work at HPD event
Patch 13 changes to use suspend_late/resume_early/resume_noirq pm ops

This series depends on improvements made in the series "drm: bridge:
dw_hdmi: Misc enable/disable, CEC and EDID cleanup" [1].
