Stephen Warren 019bc6259d ARM: tegra: enable PCI support of p2371-2180
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.
