x86: dtb: Add support for PCI devices backed by dtb nodes
x86_of_pci_init() does two things:
- it provides a generic irq enable and disable function. enable queries
the device tree for the interrupt information, calls ->xlate on the
irq host and updates the pci->irq information for the device.
- it walks through PCI bus(es) in the device tree and adds its children
(device) nodes to appropriate pci_dev nodes in kernel. So the dtb
node information is available at probe time of the PCI device.
Adding a PCI bus based on the information in the device tree is
currently not supported. Right now direct access via ioports is used.
