The PCIe root complex on Juno translates the MMIO mapped
at 0x5f800000 to the PIO address range starting at 0
(which is common because PIO addresses are generally < 64k).
Correct the DT to reflect this.

I have another DT fix that I have asked ARM-SoC guys to pick up directly
from the list. If that doesn't happen, I will send PR including both.
If that happens then we need to send this to them to be picked directly.
At this point I want to wait for couple of days to avoid confusion.

I ended up taking the other one for v4.10, but this one seems more
important so I applied it for v4.9.
Let me know if you disagree with the priorities, as I plan to send out
the last 4.9 fixes pull request to Linus tomorrow.
