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.

On STM32MP15 variant, the configuration is enabled only during
initialization. On STM32MP13 variant, the same feature is also enabled
during initialization but the device embeds 2 more IO domains
(SDMMC1 and SDMMC2) for which the new API function allow runtime
reconfiguration support.

For sake of simplicity, keep related clocks always on.
