The RGMII PHY needs to change drive-strength properties of the Ethernet
Tx pins to stabilize the PHY.

The devicetree for LD20 global board specifies RMII PHY in the ethernet
node as default, however, there is also another board that has RGMII PHY.
The devicetree for the board doesn't exist, so the users should change
the ethernet properties by outside way.

Probably, users should change pinctrl_ether_rgmii
by the same means.

I think that it's reasonable to have a devicetree for another board with
RGMII PHY.

The change to uniphier-pxs3-ref.dts looks OK to me.

I'll split this patch for uniphier-pxs3-ref.dts.

Thank you,
