Using new DRM eDP backlight helpers, add support to create and register a backlight for those panels in drm_panel to simplify the panel drivers. The panel driver with access to "struct drm_dp_aux" can create and register a backlight device using following code snippet in its probe() function: err = drm_panel_dp_aux_backlight(panel, aux); if (err) return err; Then drm_panel will handle backlight_(enable|disable) calls similar to the case when drm_panel_of_backlight() is used. Currently, we are not supporting one feature where the source device can combine the backlight brightness levels set through DP AUX and the BL_PWM_DIM eDP connector pin. Since it's not required for the basic backlight controls, it can be added later.
