sgtl5000 has two required supplies: VDDA and VDDIO and one optional supply:
VDDD, so document this properly.

Not passing VDDA and VDDIO prevents the driver to probe successfully.

Applied, thanks.  Note that with current kernels the regulator API
should assume that most regulators are provided even if not explicitly
listed in DT.
