The Bananapi M3 has an RTL8211E PHY connected to the EMAC using
RGMII. The PHY is powered by DCDC1 through SW @ 3.3V.

The board is designed to use 3.3V with RGMII, instead of the standard
reduced voltage of 2.5V we see everywhere. DLDO3, which provides the
I/O voltages, is raised to match.

This patch enables the EMAC and Realtek PHY drivers in the defconfig.
The device tree file already has the EMAC enabled.

Changes in v3:
  - Rebased on sunxi/master

Changes in v2:
  - Dropped clk/reset related changes in favor of DM CLK / RESET support
  - Raised DLDO3 for RGMII I/O on Bananapi M3 to 3.3V per design
