drivers: pwm: nrf: Modify fade_led PWM example, use new HW drv

Browse source 
1. Modified fade_led PWM example to include
   nRF HW PWM option.
2. Added fade_led nrf52_pca10040.overlay
   in order to enable PWM node and choose
   output PWM GPIO for channel 0. Channel 1
   GPIO enable but not used in sample src.
