Zhang Yubing 82a87fa40a drm/rockchip: Add support for out-of-band hotplug notification
Add a new drm_connector_oob_hotplug_event() function and
oob_hotplug_event drm_connector_funcs member.

On some hardware a hotplug event notification may come from outside the
display driver / device. An example of this is some USB Type-C setups
where the hardware muxes the DisplayPort data and aux-lines but does
not pass the altmode HPD status bit to the GPU's DP HPD pin.

In cases like this the new drm_connector_oob_hotplug_event() function can
be used to report these out-of-band events.

Avoid the conflict of GKI, the drm_connector_oob_hotplug_event() is be
completed in rockchip drm driver, not the drm framework.
