Hisilicon Soc hip04 has four GPIO controllers, each one has 32
GPIOs and can be configured to be an interrupt controller.The GPIO
controllers are compatible with the snps,dw-apb-gpio driver.
This patch add the corresponding device tree nodes.
A new property caller "gpio-number-forward" has been added in
dw-apb-gpio dts node to support to get base number of a GPIO
controller in increasing order.
