This sets and locks all peripheral type-1 masters, except CAAM, access
as non-secure, so that they can't access secure world resources from the
normal world.
The CAAM itself is TrustZone aware and handles memory access between the
normal world and the secure world on its own. Pinning it as non-secure
access results in bus aborts if the secure memory region is protected by
the TZASC380.
