mps3-an547: Add missing user ahb interfaces
With these interfaces missing, TFM would delegate peripherals 0, 1,
2, 3 and 8, and qemu would ignore the delegation of interface 8, as
it thought interface 4 was eth & USB.
This patch corrects this behavior and allows TFM to delegate the
eth & USB peripheral to NS mode.
(The old QEMU behaviour was based on revision B of the AN547
appnote; revision C corrects this error in the documentation,
and this commit brings QEMU in to line with how the FPGA
image really behaves.)

[PMM: added commit message note clarifying that the old behaviour
was a docs issue, not because there were two different versions
of the FPGA image]
