plat/sgi: define default list of memory regions for dmc620 tzc
Define a default DMC-620 TZC memory region configuration and use it to
specify the TZC memory regions on sgi575, rdn1edge and rde1edge
platforms. The default DMC-620 TZC memory regions are defined
considering the support for secure paritition as well.
