plat/stm32mp1: sp_min relies on etzpc driver
Use ETZPC driver to configure secure aware interfaces to assign
them to non-secure world. Sp_min also configures BootROM resources
and SYSRAM to assign both to secure world only.
Define stm32mp15 SoC identifiers for the platform specific DECPROT
instances.
