This method looks better than before, but putting a single register
into DT looks wrong. I can almost guarantee that there are more
registers at 0xf8000000-0xf8000fff (or more) that belong to either
some system controller or a DMA controller.

Whatever it is, please describe it in the DT in a sensible way based
on what the hardware does and what other resources it uses (interrupts
etc) rather than what today's kernel happens to need.
