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.)
