Changes since [v2]:

- Drop pmic label

- Rename phy -> ethernet-phy

- Drop snvs_pwrkey configuration

- Move snvs_rtc up, to keep things alphabetical

- Rename debuggrp -> ledsgrp

- Collected Reviewed-by from Fabio

Changes since [v1]:

- Added missing #address-cells and #size-cells

- Replaced reset-gpio -> reset-gpios
