feat(el3-spmc): add support to map S-EL0 SP memory regions

Add the support to parse SP manifest to get memory regions, create xlat
tables and then program it in TTBR0.

SP manifest contains the info on memory map regions that are needed by
the SP. These regions needs to be mapped as SP running at S-EL0 does not
have privilege to do it.
