The only difference between GIC-500 and GIC-600 relevant to TF-A is the differing power management sequence. A certain GIC implementation is detectable at runtime, for instance by checking the IIDR register. Let's add that test before initiating the GIC-600 specific sequence, so the code can be used on both GIC-600 and GIC-500 chips alike, without deciding on a GIC chip at compile time. This means that the GIC-500 "driver" is now redundant. To allow minimal platform support, add a switch to disable GIC-600 support.
