Enable driver to utilize PWM on the Nordic Semiconductor nRF SoCs.
When used with HF timer, it provides up to 5 pins, utilizing one
GPIOTE channel and two PPI/DPPI channels and per pin.
When used with RTC, it provides up to 3 pins, utilizing one GPIOTE
channel and two or three (when the fork feature is not available)
PPI/DPPI channels per pin.
