From: Valentin Longchamp <valentin.longch...@keymile.com>
No piggy board is used here and the phy is always present, so we use
the ethernet_present from mgcoge3un where this is similar.
The phy is also configured with "RGMII clock transitions when data
stable" and "Class A driver for the direct backplane connection".
