For the GIC power management we need to identify certain GIC
implementations, so we have the IIDR values for some Arm Ltd. GIC models
defined.
We will need those number elsewhere very soon, so export them to a
shared header file, to avoid defining them again.

The GIC IP formerly known as "GIC Clayton" has been released under the
name of "GIC-700".
Rename occurences of Clayton in comments and macro names to reflect the
official name.

The Arm GIC-Clayton IP has the same power management requirements as
the GIC-600, when it comes to powering up the redistributors before
using them.
Add the IIDR value to the existing list of implementations requiring
the power sequence.

This patch adds the IIDR value for GIC600-AE to the gicv3_is_gic600()
helper function. This helps platforms supporting this version of the
GIC600 interrupt controller to function with the generic GIC driver.

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.
