x86: C1E late detection fix. Really switch off lapic timer
Doh, I completely missed that devices marked DUMMY are not running the set_mode function. So we force broadcasting, but we keep the local APIC timer running. Let the clock event layer mark the device _after_ switching it off. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu>
