The initial purpose of brightness_set_sync op, introduced along with the LED flash class extension, was to add a means for setting torch LED brightness as soon as possible, which couldn't have been guaranteed by brightness_set op. This patch renames the op to brightness_set_blocking, which describes its purpose in a more generic way, and is beneficial in view of the prospective changes in the core related to using LED core's set_brightness_work for setting brightness for LED class drivers that can sleep or use delays while setting brightness.
