FVP: Do not map DEVICE2 memory range when TBB is disabled
The DEVICE2 memory range is needed to access the Root of Trust Public
Key registers. This is not needed when Trusted Board Boot is disabled
so it's safer to not map it in this case. This also saves one level-2
page table in each of BL1 and BL2 images.
Also add some comments.
