main/linux-postmarketos-allwinner: set leds-gpio max_brightness to 1 (MR 1838)

LEDs controlled through the leds-gpio driver are not PWM capable.
Setting the max_brightness property to 1 instead of 255.

+Subject: [PATCH] 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.
