feat(fvp): add Dualroot CoT in DTB support

Adding support for Dualroot CoT in DTB. This makes it possible for BL2
to retrieve its chain of trust description from a configuration file in
DTB format. With this, the CoT description may be updated without
rebuilding BL2 image.

This feature can be enabled by building BL2 with COT_DESC_IN_DTB=1 and
COT=dualroot. The default behavior remains to embed the CoT description
into BL2 image.
