In the add-on file for the GIC dealing with the RealView family
we currently only handle the PB11MPCore, let's extend this to
manage the RealView EB ARM11MPCore as well. The Revision B of the
ARM11MPCore core tile is a bit special and needs special handling
as it moves a system control register around at random.

ChangeLog v1->v2:
- Detect syscon register location based on the syscon compatible
  string instead of the GIC compatible string, just define one
  compatible string for the 11mp test chip GIC.
- Consistently return -ENODEV
This can be applied in isolation from the other patches so Marc
one you're happy with it, please take it into the IRQchip tree.
