[PATCH v2 12/15] dt-bindings: media: add the stm32mp25 compatible of DCMIPP

[Alain Volmat <alain.volmat@xxxxxxxxxxx>]

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).

Signed-off-by: Alain Volmat <alain.volmat@xxxxxxxxxxx>
