    acpi_timer(4): Remove unused 'acpi_timer_disabled' boolean
    
    Same reason as for the previous commit to acpi_cpu(4).  This boolean is
    not used anywhere.  Disabling acpi_timer(4) can be done through the
    regular ACPI disable mechanism (using the 'debug.acpi.disabled' tunable,
    see acpi_disabled()).
