At present USB devices with no driver model driver cannot be seen in the
device list, and we fail to set them up correctly. This means they cannot
be used.
While having real drivers that support driver model for all USB devices
is the eventual goal, we are not there yet.
As a stop-gap, add a generic USB driver which is bound when we do not have
a real driver. This allows the device to be set up and shown on the bus.
It also allows ad-hoc code (such as usb_ether) to find these devices and
set them up.

USB devices in U-Boot are currently probed only after all devices have
been enumerated. Each type of device is probed by custom code, e.g.:
- USB storage
- Keyboard
- Ethernet
With driver model this approach doesn't work very well. We could build
a picture of the bus and then go back and add the devices later, but
this means that the data structures are incomplete for quite a while.
It also does not follow the model of being able to bind a device when we
discover it.
We would prefer to have devices automatically be bound as the device is
enumerated. This allows us to attach drivers to particular USB classes
or product/vendor IDs. This is the method used by Linux.
Add the required #defines from Linux, a way of declaring a USB driver and
the logic to locate the correct driver given the USB device's descriptors.

The U-Boot device trees are slightly different in a few places. Adjust them
