ACPI: Don't let acpi_pad needlessly mark TSC unstable
acpi pad driver kind of aggressively marks TSC as unstable at init time, on mwait capable and non X86_FEATURE_NONSTOP_TSC systems. This is irrespective of whether pad driver is ever going to be used on the system or deep C-states are supported/used. This will affect every user who just happens to compile in (or get a kernel version which compiles in) acpi pad driver. Move mark_tsc_unstable() out of init to the actual idle invocation path of the pad driver. There is also another bug/missing_feature in the code that it does not support 'always running apic timer' and switches to broadcast mode unconditionally. Shaohua, can you take a look at that please.
