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.

Hmm, the S905 public data sheet[1] shows this as GPIOAO_13.

gack, nevermind.  I see now this is for GXL, not GXBB.  Ignore my comments.

Linus, feel free to apply with:
