In case of "st,stm32mp1-rcc-secure" (stm32mp1 clock driver with RCC

It looks like this should rather be a property than a compatible string
-- the compatible string is used by the OS to determine which hardware
is represented by a node, but here it is the same hardware in either
case, "st,stm32mp1-rcc" and "st,stm32mp1-rcc-secure", it is still the
same STM32MP1 RCC block, just configured differently by some bootloader
stage.
So why not just add one-liner property of the RCC block like ?
st,rcc-in-secure-configuration
