From: Gabriel Fernandez <gabriel.fernandez@foss.st.com>

This change reflects board hardware configuration where RCC security
features are configured for RCC[TZEN]=1 and RCC[MCKPROT]=0, that is
RCC TrustZone is hardened and RCC MCKPROT is disabled.

Clock and reset controllers that relate to SoC secure resources are
moved from a RCC clock/reset handle to a SCMI clock/reset_domain handle.

These clocks are all the platform oscillators (HSI/LSI/CSI/HSE/LSE),
clocks for few subsystem and peripheral interfaces.

This change add a SCMI clock dependency on RCC clock device since it
registers clocks which parent clocks are provided by the SCMI clock
driver. This change allows the RCC clock device probe to be deferred
until SCMI clocks are fully registered in the system.

This would break existing boards, right? If so, you should move the
last patch in the series before this one and patch all existing boards
to use it. Maintainers of individual boards can then opt-in later by
deleting the arch/arm/boot/dts/stm32mp15-no-scmi.dtsi inclusion.

Cheers,
Ahmad
