Changes since v3:
- Implements hpd_notify instead of oob_hotplug_event
- Rebased on new cleanup patch from Dmitry
- Set hpd_state to ST_MAINLINK_READY when dp_display_usbpd_configure() succeeds
drivers/gpu/drm/msm/dp/dp_display.c
() and let
drivers decide whether they would like to receive the event or not.

Implement the oob_hotplug_event() callback. Translate it to the HPD
notification sent to the HPD bridge in the chain.
