So a note from an upstream kernel thread [1] and basically there needs
to be a new DW HDMI audio driver rather than "simple audio card",
apparently it's almost done but it hasn't been posted for review and
that may take some time.

Looking through the kernel tree, they don't have the audio driver for the sun4i HDMI device merged (there was a v3 of the patch series proposing it over a year ago, but I haven't found anything since). Since it isn't in the upstream kernel, you won't have that config option available in a Fedora kernel sources.
