Setup pwm lines as follows -
pwm1: In case HummingBoard base carrier; this pin drives through a serial
capacitor the mono out of the audio jack.
In case HummingBoard pro the this pad can be reached by wiring to
C8 capacitors on the board.
pwm2: Setup pwm2 on gpio-1 but leave the default function of the iopad as
a gpio.
The user can change the io pad mux in user space and therefore use
this function on gpio-1 (pin number 7 on the 26 pin header).
pwm3,pwm4: unused
