de6db03b53 v4l2transform: Don't rank it for now 
This will prevent the converter to be picked automatically in case
someone implement dynamic converter selection support. I'd like this
to be ranked only for known device, as it's hard to be sure a device is
a converter suited for general purpose. Re-negotiation is also needed
before we can rank it.

077fcbcf15 v4l2: Cleanup M2M properties 
M2M devices were sharing the same properties as src and sink. Most of
these made no sense. This patch reduces the number of propeties and
makes io-mode clearer by having capture-io-mode and output-io-mode. This
also accidently fixed a bug in gstv4l2transform io-mode code, where the
capture io-mode could not be set.

a4b5811d22 v4l2: Split flush in start/stop_streaming 
This allow calling start streaming later for capture device. Currently it breaks
in dmabuf-import because downstream is holding a buffer that will only be
released after stream-start.

82a806e63b v4l2: Replace miss-use of crop meta in favour of proper offset 
This moves away from copying information and store everything inside
the GstVideoInfo structure. The alignement exposed by v4l2 api
is now handled using proper offset.
