gpio: rockchip: convert to dynamic GPIO base allocation

This driver is used on device tree based platform. Use dynamic
GPIO numberspace base to suppress the warning:

gpio gpiochip0: Static allocation of GPIO base is deprecated, use dynamic allocation.
gpio gpiochip1: Static allocation of GPIO base is deprecated, use dynamic allocation.
gpio gpiochip2: Static allocation of GPIO base is deprecated, use dynamic allocation.
gpio gpiochip3: Static allocation of GPIO base is deprecated, use dynamic allocation.
gpio gpiochip4: Static allocation of GPIO base is deprecated, use dynamic allocation.
