serial: st-asc: Don't call BUG in asc_console_setup() In order to prevent an asc instance to be used as early console, BUG_ON is used on either mapbase or membase being NULL. Problem is that this condition is also true when we set console to be a ttyASx different to the first asc instance being probed. Instead of calling BUG_ON, it now returns -ENXIO when either mapbase or membase is NULL.
