Allocate and register drm_panel to allow the panel_follower framework to
detect the eDP panel and pass drm_connector::kdev device to drm_panel

Call drm_panel_prepare/unprepare in ddi_enable for eDP to allow the
followers to get notified of the panel power state changes.
Note: This is for eDP with DDI platforms only.
