Wish: support GPIO mux #2

It was tested on Intel Edison PWM0 (50 Hz on buzzer)
Note that GPIO12 must be manually configured first, using:
```sh
gpio=12
echo $gpio | sudo tee -a /sys/class/gpio/export
echo out | sudo tee /sys/class/gpio/gpio$gpio/direction
echo mode1 | sudo tee /sys/kernel/debug/gpio_debug/gpio${gpio}/current_pinmux
```
More/Better gpio drivers maybe added later,
for the record 'pwm' one was prefered here
as base for webthing-iotjs (API to be aligned with IoT.js),
but pwm module is lacking muxing support.
It can be used to control servo motors, for more check:

As mentionned in
#1
GPIO muxing is lacking, It was needed for edison
If this project is no more maintained:
may this be done in related project that would merge pwm support through sysfs ?
