backlight: tps65217_bl: Add missing platform_set_drvdata in tps65217_bl_probe
Otherwise, we got NULL derefernce while calling backlight_device_unregister() in tps65217_bl_remove(). Also convert to use module_platform_driver. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
