This commit introduces support for using SPs from the FIP. TF-A offers a
mechanism to encapsulate an SP image and its manifest into an SP package
and add that to the FIP. During boot BL2 will load these packages into
memory and the SPMC manifest is used to pass the load addresses to the
SPMC. The SP package contains a header, the SP manifest and the SP image
itself [1].
For loading the SP packages the existing embedded SP handling code is
mostly reused. The only difference is that instead of a scattered array
that's created at build time the SP packages are discovered at runtime
and collected into a linked list.
