rockchip: add reset or power off gpio configuration for rk3399
We add plat parameter structs to support BL2 to pass variable-length, variable-type parameters to BL31. The parameters are structured as a link list. During bl31 setup time, we travse the list to process each parameter. throuth this way, we can get the reset or power off gpio parameter, and do hardware control in BL31. This structure also can pass other parameter to BL31 in future.

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.
