samples/gpio_dw: extends the app for GPIOs on quark_se_ss

Browse source 
The basic is the same for both architecture, but using different
GPIO controller and pins.

* --------------------
*
* On Sensor Subsystem of Arduino 101:
* 1. GPIO_SS[ 2] is on A00
* 2. GPIO_SS[ 3] is on A01
* 3. GPIO_SS[ 4] is on A02
* 4. GPIO_SS[ 5] is on A03
* 5. GPIO_SS[10] is on IO3
* 6. GPIO_SS[11] is on IO5
* 7. GPIO_SS[12] is on IO6
* 8. GPIO_SS[13] is on IO9
*
* There are two 8-bit GPIO controllers on the sensor subsystem.
* GPIO_SS[0-7] are on GPIO_0 while GPIO_SS[8-15] are on GPIO_1.
*
* The gpio_dw driver is being used. The first GPIO controller
* is mapped to device "GPIO_0", and the second GPIO controller
* is mapped to device "GPIO_1".
*
* This sample app toggles GPIO_SS_2/A0. It also waits for
* GPIO_SS_3/A1 to go high and display a message.
*
* If A0 and A1 are connected together, the GPIO should
* triggers every 2 seconds. And you should see this repeatedly
