I see now this is for GXL, not GXBB. Ignore my comments. Linus, feel free to apply with: Acked-by: Kevin Hilman <khilman@baylibre.com>

This adds support for the pwm_ao_b pin. Unfortunately the registers for the pwm_ao pins are not documented at all. The source for the pwm_ao_b pin from this patch is the Khadas VIM GPL kernel source, which sets bit 3 and unsets bits 4 and 31 to enable the PWM LEDs.
