ARM: dts: rockchip: correct interrupt flags on rk3188 boards

GPIO_ACTIVE_x flags are not correct in the context of interrupt flags.
These are simple defines so they could be used in DTS but they will not
have the same meaning:
1. GPIO_ACTIVE_HIGH = 0 = IRQ_TYPE_NONE
2. GPIO_ACTIVE_LOW  = 1 = IRQ_TYPE_EDGE_RISING

Correct the interrupt flags without affecting the code:
  ACTIVE_HIGH => IRQ_TYPE_NONE
