Describe the GPIO used to reset the Ethernet PHY for EthernetAVB. This allows the driver to reset the PHY during probe and after system resume. On ULCB, the enable pin of the regulator providing PHY power is always pulled high, but the driver may still need to reset the PHY if this wasn't done by the bootloader before. Inspired by patches in the BSP for the individual Salvator-X/XS boards by Kazuya Mizuguchi.
