ARM: tegra: apalis-tk1: Hog group for ethernet, PCIe, reset GPIOs
The Apalis TK1 module uses some dedicated GPIOs as I210 gigabit Ethernet
controller reset and to control RESET_MOCI aka reset module output
carrier input on MXM3 pin 26. The Apalis Evaluation Board furthermore
uses Apalis GPIO7 on MXM3 pin 15 as reset signal for its PLX PEX 8605
PCIe Switch.
