plat/arm/board/arm_fpga: Initialize the Generic Interrupt Controller
This initializes the GIC using the Arm GIC drivers in TF-A.
The initial FPGA image uses a GIC600 implementation, and so that its
power controller is enabled, this platform port calls the corresponding
implementation-specific routines.
