The beep_mode=2 option was introduced to make the beep mixer controlling the beep input allocation/deallocation dynamically, so that a user can switch between HD-audio codec digital beep and the system beep only via mixer API. This was necessary because the keyboard driver took only the first input beep instance at that time. However, the recent keyboard driver already processes the multiple input instances, thus there is no point to keep this mode. Let's remove it.
