Add a directory in drivers/clk to regroup the clock drivers for all STM32 SoCs with CONFIG_ARCH_STM32 (MCUs with Cortex-M) or CONFIG_ARCH_STM32MP (MPUs with Cortex-A).

Changes in v3: - Some nits in commit message (s/Soc/SoCs/ & s/cortex /Cortex-/)
Changes in v2: - replace '_' by '-' in file names to be consistant with other clk drivers and prepare introduction of new files for stm32mp13
