fconf: Add Secure Partitions information as property
Use the firmware configuration framework to retrieve information about
Secure Partitions to facilitate loading them into memory.
To load a SP image we need UUID look-up into FIP and the load address
where it needs to be loaded in memory.
This patch introduces a SP populator function which gets UUID and load
address from firmware config device tree and updates its C data
structure.
