Add topology of the two pixel pipes (main & aux) of the stm32mp25.
Do not make the link from dcmipp_input immutable and enabled by
default since not all pipes are always used together so when a pipeline
is not being used its link should be disconnected to allow proper
pipeline check.
Not doing this would most probably lead to pipeline start failure due
to incompatible pads configurations on the unused pipe.
