fconf: Move platform io policies into fconf
Use the firmware configuration framework to store the io_policies
information inside the configuration device tree instead of the static
structure in the code base.
The io_policies required by BL1 can't be inside the dtb, as this one is
loaded by BL1, and only available at BL2.
This change currently only applies to FVP platform.
