Add the stm32mp25 compatible for the DCMIPP. The stm32mp25 distinguish with the stm32mp13 by the fact that: - supports also csi inputs in addition to parallel inputs - requires an addition csi clock to be present Add also access-controllers, an optional property that allows a peripheral to refer to one or more domain access controller(s).
