Subject: [PATCH v2 00/10] drm: bridge: dw_hdmi: Misc enable/disable, CEC and EDID cleanup

This series ensure poweron/poweroff and CEC phys addr invalidation is
happening under drm mode_config mutex lock, and also ensure EDID is
updated (when the dw-hdmi connector is used) after a hotplug pulse.

These changes has mainly been tested on Rockchip devices together with a
series [1] that add HDMI 2.0 4K@...z support to RK3228, RK3328, RK3399
and RK3568.

Rockchip use the dw-hdmi connector so this should also be validated with
a driver that use the bridge connector.

Changes in v2:
- Add patch to disable scrambler feature when not supported
- Add patch to only notify connected status on HPD interrupt
- Update commit messages
- Collect r-b tags
- Rebased on next-20240906
