Hello!
Yes, I definitely agree with this change, it makes no sense to have both
8173 and 8183 compatibles for 8183 (and similar).

Though, please, add a note in this commit message advertising that the
mistake was only in the yaml binding, as the driver doesn't require any
functional changes, so that things are clear for people with less expertise
on MediaTek platforms.

After that:
