Add the stm32_firewall_get_grant_all_access() API to be able to fetch
all firewall references in an access-controllers property and try to grant
access to all of them.

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.

bus: firewall: Fix missing static inline annotations for stubs2025-05-07T09:25:02+00:00Krzysztof Kozlowskikrzysztof.kozlowski@linaro.org2025-05-07T09:21:22+00:00urn:sha1:66db876162155c1cec87359cd78c62aaafde9257
Stubs in the header file for !CONFIG_STM32_FIREWALL case should be both
static and inline, because they do not come with earlier declaration and
should be inlined in every unit including the header.

Remove misplaced colon in stm32_firewall_get_firewall()
which results in a syntax error when the code is compiled
without CONFIG_STM32_FIREWALL.

firewall: introduce stm32_firewall framework2024-04-05T14:49:14+00:00Gatien Chevalliergatien.chevallier@foss.st.com2024-01-05T13:03:56+00:00urn:sha1:5c9668cfc6d7c7de30fa57fa0a6c0ddc93462969
Introduce a STM32 firewall framework that offers to firewall consumers
different firewall services such as the ability to check their access
rights against their firewall controller(s).
The STM32 firewall framework offers a generic API for STM32 firewall
controllers that is defined in their drivers to best fit the
specificity of each firewall.
There are various types of firewalls:
-Peripheral firewalls that filter accesses to peripherals
-Memory firewalls that filter accesses to memories or memory regions
-No type for undefined type of firewall
