devicetree: Add USB device type 

This commit adds support for describing USB ports in devicetree.cb.
It allows a USB port location to be described in the tree with
configuration information, and ACPI code to be generated that
provides this information to the OS.

A new scan_usb_bus() is added that will scan bridges for devices so
a tree of ports and hubs can be created.

The device address is computed with a 'port type' and a 'port id'
which is flexible for SOC to handle depending on their specific USB
setup and allows USB2 and USB3 ports to be described separately.

For example a board may have devices on two ports, one with a USB2
device and one with a USB3 device, both of which are connected to an
xHCI controller with a root hub:

     xHCI
       |
    RootHub
    |     |
USB2[0]  USB3[2]

device pci 14.0 on
  chip drivers/usb/acpi
    register "name" = ""Root Hub""
    device usb 0.0 on
      chip drivers/usb/acpi
        register "name" = ""USB 2.0 Port 0""
        device usb 2.0 on end
      end
      chip drivers/usb/acpi
        register "name" = ""USB 3.0 Port 2""
        device usb 3.2 on end
      end
    end
  end
end
