I assumed you'd fix up all the other SoCs affected by this, but I only
saw fixes for sm8550, sm8650 and x1e80100 in your fixes branch.

Just sent a corresponding fix for sc8280xp, which I've confirmed also
needs this for QUP:

But what about the sm8550 USB issue? Don't the other platforms also need
a corresponding fix (e.g. for when booting from USB)?
