The sunxi_cedrus_engine enum actually enumerates pretty much the codecs to use (or we can easily infer the codec engine from the codec). Since we will need the codec type as well in some later refactoring, make that structure more useful by just enumerating the codec, and converting the existing users.

Feel free to rename to cedrus_codec when rebasing on top of the latest patchset introducing the driver. Cheers, Paul
