test(boot): test suite uses to test the SPMC

Use the "boot" test suite, to validate memory range that the SP can
access its address space:
 - Added the "mem_size" to the SP's FF-A manifest, needed within the
 aforementioned tests.
 - Test services retrieve the "load-address" from the SPs FF-A manifest,
 use it to do the accesses to validate the configuration of the SPs
 address space.
