Gerd Hoffmann b791c3b38c usb: add usb_pick_speed ...

We can pick the usb port speed in generic code, by looking at the port
and device speed masks and looking for the fastest match.  So add a
function to do exactly that, and drop the speed setting code from
usb_desc_attach as it isn't needed any more.

This way we can set the device speed before calling port->ops->attach,
which fixes some xhci hotplug issues.
