[PATCH] mps3-an547: Add missing user ahb interfaces


From: Jimmy Brisson
Subject: [PATCH] mps3-an547: Add missing user ahb interfaces
Date: Thu, 10 Feb 2022 15:02:27 -0600

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.
