Mathias Nyman 6aec50009d xhci: dbc: Don't call dbc_tty_init() on every dbc tty probe ...

The current workaround to call the dbc_tty_init() in probe is
not working in case we have several xhci devices with dbc enabled.

dbc_tty_init() should be called only once by a module init call when
module is loaded.

until dbgtty is its own module call dbc_tty_init() from xhci
module init call.

Same is true for unloading and dbc_tty_exit()
