[PATCH] i386/x86-64: Remove sub jiffy profile timer support

Remove the finer control of local APIC timer. We cannot provide a sub-jiffy
control like this when we use broadcast from external timer in place of
local APIC. Instead of removing this only on systems that may end up using
broadcast from external timer (due to C3), I am going the
"I'm feeling lucky" way to remove this fully. Basically, I am not sure about
usefulness of this code today. Few other architectures also don't seem to
support this today.

If you are using profiling and fine grained control and don't like this going
away in normal case, yell at me right now.
