xfree86: remove bus state change notification callback

Browse source 
No one is using bus notifications now. We hope that the kernel take care of
this properly.

For other not-so-urgent-notifications (ACPI wakeups, etc) we can just register
a handler on server's scheduler (using xf86AddGeneralHandler). And for
external applications, the "trend" is to use HAL to kick notifications. So
we're already provided of enough notification schemes.
