at91: Fix to enable using Teridian MII phy (78Q21x3) with at91sam9260

On the at91sam9260ep development board there is an EEPROM
connected to the TWI interface (PA23, PA24 Peripheral A
multiplexing), so we cannot use these pins as ETX2, ETX3.
This patch configures PA10, PA11 pins for ETX2, ETX3
instead of PA23, PA24 pins.
