arm: mach-bcm283x: Map the ARM local MMIO as well

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.
