Allocate and register a drm_panel so that drm_panel_followers can find the panel. Pass the drm_connector::kdev device to drm_panel allocation for matching. That's only available after drm_sysfs_connector_add(), so we need to postpone the drm_panel allocation until .late_register() hook. The drm_panel framework is moving towards devm_drm_panel_alloc(). It requires a wrapper struct, and struct intel_panel would be the natural candidate. However, we can't postpone its allocation until .late_register(), so we have to use __devm_drm_panel_alloc() directly for now. Call the drm_panel_prepare() and drm_panel_unprepare() functions for ICL+ DSI, so that followers get notified of the panel power state changes. This can later be expanded to VLV+ DSI and eDP.
