It is highly unlikely, this function is called when uart is already
working and pinmux is set.

But if we assume that pinmux is not set, then how we resolve situation
when pinmux and regulator enable are both set by probe after bind and
regulators are probed before pinmux. Regulators will fail, they will
not deffer till pinmux probes. Or you propose return to pre-DM version
of pinmux? Inconsistency.
