ASoC: sgtl500: Document the required supplies
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. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Signed-off-by: Mark Brown <broonie@kernel.org>
