This patch adds run-time detection of avaiable timer features so that we can treat Medfield as a variant of Moorestown and set up the optimal timer options for each platform. i.e. Medfield: per cpu always-on local APIC timer Moorestown: per cpu APB timer Manual override is possible via cmdline option x86_mrst_timer.
