Nicolas Dufresne 33aafc4a91 v4l2codecs: Sort formats to avoid quality lost ...

When the driver prefered format is not picked by downstream, the
decoders needs to select another format from the list. The selection
was currently unsorted, resulting in 10bit data often being stripped
to 8bit.

To solve this, reorder the formats in an HW preference order. This order
deviates slightly from the preferred order in libgstvideo. This is to
prefer bandwidth saving over better CPU alignment. As an example NV15 is
prefered over P010. We also prefer tiled over linear.
