From: Claudiu Beznea <claudiu.beznea@microchip.com> commit 221c3a09ddf70a0a51715e6c2878d8305e95c558 upstream. Fix the phy address to 7 for Ethernet PHY on SAMA5D27 SOM1. No connection established if phy address 0 is used. The board uses the 24 pins version of the KSZ8081RNA part, KSZ8081RNA pin 16 REFCLK as PHYAD bit [2] has weak internal pull-down. But at reset, connected to PD09 of the MPU it's connected with an internal pull-up forming PHYAD[2:0] = 7.
