fix(fvp): extend memory map to include all DRAM memory regions
Currently only the lowest 2 DRAM region were configured in the
TrustZone Controller, but the platform supports 6 regions spanning the
whole address space.
Configuring all of them to allow tests to access memory also in those
higher memory regions.
FVP memory map:
https://developer.arm.com/documentation/100964/1116/Base-Platform/Base---memory/Base-Platform-memory-map
Note that last row is wrong, describing a non-existing 56bit address,
all region labels should be shifted upward.
Issue has been reported and next release will be correct.
