Cover the "ARM local MMIO" range as well in the default MMU mapping in order to allow future code to access the GIC-400 without crashing. For now the GIC is not touched in u-boot, thus this change is a noop.
See [1](BCM2711 ARM Peripherals) for reference.
TEST: Enabled CONFIG_GICV2 and accessed the GIC in C code without crash.
