arm: apple: t602x: Add missing MMIO regions to memmap
The memory maps for Apple's M2 Pro/Max/Ultra left MMIO space out which
was not used by any driver at the time. The display out exposed as
simple-framebuffer use a power-domain controlled by a device in an
unmapped region.
Add a map covering this region as well as another MMIO region in the
range 0x4'0000'0000 - 0x5'0000'0000. The added regions cover all MMIO
annotated in Apple's device tree in this range.
