Just like the Bananapi M2 Ultra, the Bananapi M2 Berry has a Realtek
RTL8211E RGMII PHY tied to the GMAC.
The PMIC's DC1SW output provides power for the PHY, while the ALDO2
output provides I/O voltages on both sides.

The PIO banks regulators addition should be in a separate
patch. Otherwise, the comments I made on patch 1 still apply.
