Note, numbering for this series starts from v5, since there were several
revisions for this patchset under a different series title ([1]).

USB altmodes code would send OOB notifications to the drm_connector
specified in the device tree. However as the MSM DP driver uses
drm_bridge_connector, there is no way to receive these event directly.
Implement a bridge between oob_hotplug_event and drm_bridge's
hpd_notify.

Merge strategy: since this series touches i915 code, it might make sense
to merge it through drm-intel.

Changes since v5:
- Fixed checkpatch warning in the first patch (noted by intel-gfx CI).

Changes since v4:
- Picked up the patchset
- Dropped msm-specific patches
- Changed drm_bridge_connector_oob_hotplug_event to call connector's HPD
  callback directly, rather than going through the last bridge's
  hpd_notify
- Added proper fwnode for the drm_bridge_connector
