pinctrl: meson: meson-gxl: add the pwm_ao_b pin
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.
