dt-bindings: clocks: stm32mp25: add description of all parents 



RCC driver uses '.index' to define all parent clocks instead '.names'
because the use of a name to define a parent clock is discouraged. This
is an ABI change, but the RCC driver has not yet merged, unlike all
others drivers besides Linux.
