node associated with the device. In preparation for supporting a live
device tree, which uses a node pointer instead, refactor existing code to
access this field through an inline function.

This patch adds a driver for the Xilinx AXI bridge for PCI express, an

mostly a case of implementing PCIe ECAM specification, but with some
quirks about what devices are valid to access.
