This adds the missing pins for the PWM controllers found in Amlogic Meson8 SoCs. This includes the pins for PWM_A, PWM_B, PWM_C, PWM_D, PWM_E and PWM_F controllers. There is an additional PWM function with the name PWM_VS in the vendor kernel sources which seems to be used for external video input. Thus it's not part of this change as the IP block behind the pwm-meson driver is not responsible for these pins.
