augustss 935b0481a9 Introduce an extra driver level for HID devices, uhidev. This uhidev driver
attaches to the hub, and HID drivers (ums, ukbd, and uhid) attach to
uhidev.  The reason for this change is that some HID devices report multiple
components (like a keyboard and a mouse) using the same interface, but with
different report identifiers.  The report identifier can be specified with
a locator for the HID drivers.
Furthermore, change the ukbd driver to handle other formats than the boot
protocol.
