drivers: firewall: stm32_etzpc: remove header file

Remove stm32_etzpc.h header file that is not required since the
declared and defined resources are used internally in stm32_etzpc.c

By the way, also remove inclusion of stm32mp15-etzpc.h DT bindings
header file from stm32_rng.c where it is not needed.

firewall: stm32_etzpc: check consistency of RCC vs DECPROT secure config

Ensures that when an ETZPC DECPROT configuration is secure (resp.
MCU isolated) that SoC RCC is also secure (resp. MCKPROT isolated).

This change helps to remove dependency on shared_resource.c driver
that is no longer needed since integration of the firewall framework.

By the way, fix include files order.

drivers: stm32_etzpc: new driver to use firewall API

Implement stm32_etzpc.c driver in the firewall driver directory.
Use the new firewall API to populate the firewall bus and register
the ETZPC as a firewall provider.

Implement a driver specific firewall bus probe that will
only probe secure peripherals and implement firewall exceptions for
which no firewall operations will be done when CFG_INSECURE is set.
This allows, for example, to share a console with the non-secure world
for development purposes.

The ETZPC driver register the following ops:
-set_conf
-acquire_access
-acquire_memory_access
