[edk2] [PATCH] ArmPkg ArmVirtPkg: fix the GIC base address variables as 64-bit

[Dennis Chen]

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.
