Enable Ethernet{0,1} interfaces on RZ/G2UL SMARC EVK. Ethernet0 pins are muxed with CAN0, CAN1, SSI1 and RSPI1 pins and Ethernet0 device selection is based on the SW1[3] switch position. Set SW1[3] to position OFF for selecting CAN0, CAN1, SSI1 and RSPI1. Set SW1[3] to position ON for selecting Ethernet0. This patch disables Ethernet0 on RZ/G2UL SMARC platform by default.
