feat(st-drivers): add RIFSC driver

RIFSC (RIF Security Controller) is responsible for the isolation
of hardware resources like memory or peripherals. It is composed of:

-RISC registers(slave peripherals) with RISUP(Resource Isolation
Slave Unit for Peripherals) OR RISAL(Resource Isolation Slave Unit
for Address space - Lite) logics.
-RIMC registers(Non RIF-Aware masters counterpart) with RIMU
(Resource Isolation Master Unit) logic. It is possible for a master to
inherit from its slave port(RISUP) configuration.

This doesn't support semaphore acquisition.

feat(st-drivers): add RISAF driver

Introduction of Resource Isolation Slave for Address space - Full
(RISAF) driver to configure main memory regions with access rights
defined in device node in DT(through FCONF compliance) or statically.

The driver is enabled as BL2 sources. Add driver-related platform
services.
RISAF base addresses and key size are set in platform definitions.
