drm/i915/panel: register drm_panel and call prepare/unprepare for eDP
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
allocation for matching.
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.
v2: remove backlight setup from panel_register (Jani)
v3: Updated the commit message (Jani)
