STM32: Mass conversion of boards to dts based clock control configuration

[erwango]

Following merge of #34120, #34609 (done) and https://github.com/zephyrproject-rtos/zephyr/pull/34701 (on-going), dts based clock control configuration will be made available to all STM32 based boards.

This opens the way to a cleaner clock control management on STM32 based targets:

• centralize handling of alternative clocks (like LSE which is controlled directly in various drivers for now)
• simplify/clean up clock control driver
• introduce alternative clock source selection
• deeper control of clocks in power management (thanks to nodes dependency information provided by device tree)

Though, before doing so, we need to ensure existing Kconfig scheme is not used anymore, in tree and out of tree. This requires to:

• convert in tree users
• deprecate Kconfig scheme and wait for deprecation period to ensure out of tree users have time to take this change into account.

Since this deprecation period will take time, it is requested to convert in tree users and proceed to Kconfig deprecation within DV2.6.0.

Note: Aside from configuration part, this change doesn't introduce change in existing driver behavior. So the risks are limited.
