x86: I/O APIC: remove parameters to fiddle with the 8259A
Remove the "disable_8254_timer" and "enable_8254_timer" kernel parameters. Now that AEOI acknowledgements are no longer needed for correct timer operation, the 8259A can be kept disabled unconditionally unless interrupts, either timer or watchdog ones, are actually passed through it.
