691fdb85c0 v4l2codecs: fix v4l2codecdevice get type
Currently the GType of v4l2codecdevice is hardcoded to zero, but it
rather should be delivered by the GType system.

6d9c98ae5a v4l2codecs: Add device enumeration
This introduces a GstV4L2CodecDevice structure and helper to retrieve a
list of CODEC device drivers. In order to find the device driver we
enumerate all media devices with UDEV. We then get the media controller
topology and locate a entity with function encoder or decoder and make
sure it is linked to two V4L2 IO entity pointing to the same device
node.
