Incorporate pm runtime framework into DP driver and clean up eDP
by moving of_dp_aux_populate_bus() to probe().
Kuogee Hsieh (8):
drm/msm/dp: tie dp_display_irq_handler() with dp driver
drm/msm/dp: rename is_connected with link_ready
drm/msm/dp: use drm_bridge_hpd_notify() to report HPD status changes
drm/msm/dp: move parser->parse() and dp_power_client_init() to probe
drm/msm/dp: incorporate pm_runtime framework into DP driver
drm/msm/dp: delete EV_HPD_INIT_SETUP
drm/msm/dp: add pm_runtime_force_suspend()/resume()
drm/msm/dp: move of_dp_aux_populate_bus() to eDP probe()

Currently DP driver use drm_helper_hpd_irq_event(), bypassing drm bridge
framework, to report HPD status changes to user space frame work.
Replace it with drm_bridge_hpd_notify() since DP driver is part of drm
bridge.
