In early stages (pre ramstage), we have two notions of devices.
To access the hardware, "simple device" handles are used. These
are plain numbers. To access the static information of the device
tree, we use `struct device` pointers. This is referred to as
DEVTREE_EARLY in the code.
This file is about the latter and its name reflects that the
tree remains unmodified.

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

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
