leds: gpio: Set max brightness to 1
GPIO LEDs only know 2 states: ON or OFF and do not have PWM capabilities. However, the max brightness is reported as 255. This patch sets the max brightness value of a GPIO controlled LED to 1. Tested on my PinePhone 1.2. Signed-off-by: Dylan Van Assche <me@dylanvanassche.be> Signed-off-by: Pavel Machek <pavel@ucw.cz>
