uio_hv_generic: Bind to FCopy device by default

Browse Source 
The Hyper-V kernel-mode fcopy driver was removed in 6.10 and the new
fcopy daemon requires this uio driver to function.  However, by
default the driver does not bind to any devices, and must be
configured through the sysfs "new_id" file.

Since the FCopy device is now only usable through this driver, add its
ID to the driver's ID table so that the daemon will work "out of the
box".
