[PATCH v7 0/3] Register the STM32MP25 RCC driver as an access controller.

["Clément Le Goffic" <legoffic.clement@gmail.com>]

The STM32MP25 RCC peripheral as an access controller is allowed to know
whether the clocks are secured or not.
The STM32MP25 RCC peripheral knows about the clock secure configuration
of all non RIF-aware peripheral.
In parallel all the RIF-aware peripheral configuration information
are known by the RIFSC peripheral which is already an access
controller.

This v7 is a subset of the v6 and other prior versions, split to simplify
the review and merging process.

Changes in v7:
- None
- Link to v6: https://lore.kernel.org/all/20250909-b4-ddrperfm-upstream-v6-2-ce082cc801b5@gmail.com/
