ARM: tegra: Enable PCIe on Beaver
The Beaver has an ethernet NIC connected to the PCIe bus. Enable the PCIe controller and the network device driver so that the device can boot over the network. In addition the board has a mini-PCIe expansion slot. Signed-off-by: Thierry Reding <treding@nvidia.com> Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>
