Subject: [PATCH] platform: Add Edison board to test PWM (#99)

It was tested on Intel edison on PWM0
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
```
