This patch relocates the device tree to the new system RAM base before
the RMM is installed in RAM. From there, other accesses to the device
tree are using the new location.

refactor(qemu): move GPT setup to BL31

Some platforms such as QEMU-SBSA access the device tree located at the
bottom of the non-secure RAM from BL31. When GPT checks are enabled at
BL2, that access generates a GPT check fault because the device tree
area is configure as non-secure RAM and the access is made from secure
EL3.

We could change the device tree memory area configuration in a way that
it is accessible from BL31, but that would require another configuration
of the GPT before going to BL33.

Since BL2 and BL31 are both running at EL3, a better solution is simply
move the GPT configuration and enabling to BL31, after the device tree
has been probed.

No change in functionality.
