Since ACPI spec defines the GIC base addresses (CPU interface,
Distributor and Redistributor*GICv3 only*) as 64-bit, so we should
define these corresponding base address variables as 64-bit instead of
32-bit. This patch redefines them according to the ACPI spec.

Following on with Ard's comment on the earlier version, what happens
if you want to use GICv3 on a 32bit system, eg the Cortex-A32 FVP
models, which I believe [1] has GICv3?
[1] Go here and search for "gicv3"

I don't think that matters. GICv3 does not use MMIO for the CPU
interface anyway, and referring to the MMIO bits using 64-bit types is
unlikely to affect performance imo. From a functionality pov, those
top bits will simply be always zero (much like they are now on every
known ARM platform)
