plat/sgi: allow access to TZC controller on all chips

On a multi-chip platform, the boot CPU on the first chip programs the
TZC controllers on all the remote chips. Define a memory region map for
the TZC controllers for all the remote chips and include it in the BL2
memory map table.

In addition to this, for SPM_MM enabled multi-chip platforms, increase
the number of mmap entries and xlat table counts for EL3 execution
context as well because the shared RAM regions and GIC address space of
remote chips are accessed.
