various irqchips and also ACPI doesn't support irqchips which
are not compatible with ARM GIC spec, so GIC version can be used
to load different GIC drivers which is needed for the later patch.

As GICR base in MADT GICC is another way to indicate the GIC version
is 3 or 4, add its support to find out the GIC versions.
