Ok, I agree...

But, at this point, can we rename `rt1019p` to `speaker_codec` instead?

Imo, that makes a bit more sense as a phandle, as it reads generic and it's not
screaming "I'm RT1019P" on dts(i) files where it's actually not.

Well, that's not a fix - it's an improvement, so we can avoid this Fixes tag :-)
