xhci: dbgtty: Make some functions static
The sparse tool complains as follows: drivers/usb/host/xhci-dbgtty.c:401:5: warning: symbol 'xhci_dbc_tty_register_device' was not declared. Should it be static? drivers/usb/host/xhci-dbgtty.c:452:6: warning: symbol 'xhci_dbc_tty_unregister_device' was not declared. Should it be static? After commit 6ae6470bfa33 ("xhci: dbc: Add a operations structure to access driver functions"), those functions are not used outside of xhci-dbgtty.c, so this commit marks them static.
