> Platform STM32MP1 can be used in configuration where some clock

> state of the CPU(s).
> In such configuration, the RCC clock driver must not register clocks
> it cannot access.
> They are expected to be registered from another clock driver such

> This change uses specific compatible string "st,stm32mp1-rcc-secure"
> to specify RCC clock driver configuration where RCC is secure.
