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.
