698753e4a5 bus: firewall: move stm32_firewall header file in include folder 
Other driver than RIFSC and ETZPC can implement firewall ops, such as
RCC.
In order for them to have access to the ops and type of this framework,
we need to get the `stm32_firewall.h` file in the include/ folder.

2eeb74c449 bus: etzpc: introduce ETZPC firewall controller driver 
ETZPC is a peripheral and memory firewall controller that filter accesses
based on Arm TrustZone secure state and Arm CPU privilege execution level.
It handles MCU isolation as well.
