drm: Add HPD state to drm_connector_oob_hotplug_event()
In some implementations, such as the Qualcomm platforms, the display
driver has no way to query the current HPD state and as such it's
impossible to distinguish between disconnect and attention events.
Add a parameter to drm_connector_oob_hotplug_event() to pass the HPD
state.
Also push the test for unchanged state in the displayport altmode driver
into the i915 driver, to allow other drivers to act upon each update.
