Neil Armstrong 3f68124c56 bindings: pcie: add pci-host-ecam-generic bindings 
Add bindings for a generic PCIe Controller in ECAM mode.

ECAM stands for PCI Express Enhanced Configuration Access Mechanism
where the PCIe config space is flat memory-mapped.

An optional msi-parent phandle is added to link to an optional
MSI/MSI-X Interrupt Message Translation HW component.

Johan Hedberg 7a2bddd75a dts: bindings: Add binding for PCIe bus 
Add a binding to represent a PCIe bus. This way PCIe devices can be
ordered under a parent PCIe bus object and make help of DT BUS macros
for conditional code.
