ARM: dts: stm32: explicit clocks needed by RCC clock driver into stm32mp151.dtsi

Browse Source 
Define in the RCC clock provider node which root clocks the driver
depends on. These are root oscillators, which may be present or
not, upon FDT content.

For "st,stm32mp1-rcc-secure", these clocks are provided by
secure world with SCMI server. For "st,stm32mp1-rcc" these clock should
provided by fixed clock.

This "clocks" property is optional but is required for bootloaders
drivers (U-Boot) to manage booth compatible "st,stm32mp1-rcc-secure"
and "st,stm32mp1-rcc" with the same driver.
