Add PSCI support to reset and power-off the board. Because this board can be used without TF-A, supply a (mandatory) PSCI implementation.
The armv8 u-boot part already contains most bits for the implementation, it is just, that it isn't compatible with the layerscape parts. Thus, we first need to clean that up and then we can add our three little functions for the PSCI support.
