plat/synquacer: enable SPM support
Enable the deprecated SPM framework for the SynQuacer platform.
It involves creating a memory layout in secure DRAM, and wiring
up the SPM infrastructure so that the secure partition payload
that is loaded into this region by the SCP firmware is dispatched
appropriately.
