p2371-2180 has two PCI ports; a regular x4 slot and a x1 M.2 slot. This patch adds the relevant DT to enable the PCI controller and configure the XUSB padctl pin muxing, and code to turn on the PCI power and enable PCI features in U-Boot. I have only tested the x4 slot. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>
