ARM: dts: rockchip: use pin constants to describe gpios

Use macros to describe gpios will make the dts easier to
read and write.

All the modifications done with sed:

sed -i -e 's/ 0  GPIO_ACTIVE_/ RK_PA0 GPIO_ACTIVE_/' arch/arm/boot/dts/rk*
sed -i -e 's/ 1  GPIO_ACTIVE_/ RK_PA1 GPIO_ACTIVE_/' arch/arm/boot/dts/rk*
sed -i -e 's/ 2  GPIO_ACTIVE_/ RK_PA2 GPIO_ACTIVE_/' arch/arm/boot/dts/rk*
.......
.......
sed -i -e 's/ 30 GPIO_ACTIVE_/ RK_PD6 GPIO_ACTIVE_/' arch/arm/boot/dts/rk*
sed -i -e 's/ 31 GPIO_ACTIVE_/ RK_PD7 GPIO_ACTIVE_/' arch/arm/boot/dts/rk*

Tested with:

for i in dts-old/*dtb; do scripts/dtc/dtx_diff $i dts-new/$(basename $i);  done
