Add "st,stm32mp25-ltdc" compatible for SOC MP25. This new SOC introduce new clocks (bus, ref & lvds). Bus clock was separated from lcd clock. New sources are possible for lcd clock (lvds / ref). Signed-off-by: Yannick Fertre <yannick.fertre@foss.st.com> --- Changes in v3: Add max/min Items fields. 'make dt_binding_check' command fails on previous patch, rework fiedls mas/min items of properties clocks & clock-names.
