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()
