60f81bfc98 clk: stm32mp2: use of STM32 access controller
Use an STM32 access controller to filter the registration of clocks.
If a clock is used by the security world, then it must not registered.

30500c2ad9 clk: stm32mp1: use stm32mp13 reset driver
STM32MP15 is now using the same reset driver as STM32MP13 as they
have the same binding requirement.

637cee5ffc clk: stm32: Introduce STM32MP13 RCC drivers (Reset Clock Controller)
This driver manages Reset and Clock of STM32MP13 soc.
It uses a clk-stm32-core module to manage stm32 gate, mux and divider
for STM32MP13 and for new future soc.

All gates, muxes, dividers are identify by an index and information
are stored in array (register address, shift, with, flags...)
This is useful when we have two clocks with the same gate or
when one mux manages two output clocks.
