rockchip: support rk3399 gpio driver
There are 5 groups of GPIO (GPIO0~GPIO4), totally have 122 GPIOs
on rk3399 platform.
The pull direction(pullup or pulldown) for all of GPIOs are
software-programmable.
At the moment, we add the gpio basic driver since reset or power off
the devices from gpio configuration for BL31.
