Message:

usbdev: refactoring

The device_rem driver callback was renamed to device_remove. Also,
a new device_removed callback was introduced. This callback will fire
after all device pipes (endpoints, internally) are unregistered from
the HC device after a call to device_remove. It is semantically
a better opportunity for the USB device driver to free resources and
join all fibrils, since endpoint unregistration will force abort all
active transfers, waking up their issuers.
