tegra: colibri_t30: asix usb ethernet reset regression

Fix ASIX USB to Ethernet reset which due to the new driver model Tegra
GPIO driver changes now requires a label string to be provided
otherwise the reservation and subsequent direction/value calls will
fail.

This fixes a regression introduced by commit:
