Peter Zijlstra bd9240a18e x86/apic: Add TSC_DEADLINE quirk due to errata
Due to errata it is possible for the TSC_DEADLINE timer to misbehave
after using TSC_ADJUST. A microcode update is available to fix this
situation.

Avoid using the TSC_DEADLINE timer if it is affected by this issue and
report the required microcode version.

[ tglx: Renamed function to apic_check_deadline_errata() ]
