ARM: dts: imx: update #interrupt-cells for gpio nodes

Browse source 
Change the value of #interrupt-cells of gpio nodes from 1 to 2, so that
the gpio irq type can be specified in device tree.  Also update binding
document to make it clear.

the second cell is used to specify the gpio polarity:
0 = active high
1 = active low
- interrupt-controller: Marks the device node as an interrupt controller.
- #interrupt-cells : Should be 2. The first cell is the GPIO number.
The second cell bits[3:0] is used to specify trigger type and level flags:
1 = low-to-high edge triggered.
2 = high-to-low edge triggered.
4 = active high level-sensitive.
8 = active low level-sensitive.
