RE: High background current after disabling PWM in SoftDevice

@diode: I found the issue with the example code in the repo is that we forgot to disable the PAN#73 workaround when we disable the pwm. So if you add:

apply_pan73_workaround(PWM_TIMER, false);

and apply_pan73_workaround(PWM_TIMER2, false); (if you use 2 timers)

to the nrf_pwm_set_enabled() function when disabling.

Then the 300mA extra current consumpt should be removed.

Also adding PWM_TIMER->TASKS_SHUTDOWN = 1; could reduce the power consumption a little bit more.
