No one seems to be working on it anymore, and it really should be merged
into the already-existing btusb driver.  Also, there is not any proper
author attribution on the code (it was copied from the in-kernel
driver...)

If someone wants to pick this back up, we can easily revert this, but
for now, delete the driver.
