Disable RCC MCKPROT if not needed on STM32MP15 platforms to allow
non-secure world to control Cortex-M coprocessor. This change is needed
when RCC secure hardening is enabled (RCC[TZEN] control bit) as it
also default enable RCC MCKPROT preventing non-secure world from
accessing some coprocessor SoC resources.
This change is needed when using in tree DTS files stm32mp15*-*-scmi.dts
and non-secure world is in charge of loading and managing the
remote processor firmware.
