CPUIDLE: Handle C2 LAPIC timer & TSC stop

ACPI C2 is quite possible mapped to CPU C3 or deeper state, so
thinking from worst cases, enable C3 like entry/exit handling for C2
by default. Option 'lapic_timer_c2_ok' can be used to select simple C2
entry/exit only if the user make sure that LAPIC tmr & TSC will not be
stop during C2.
