x86, mrst: add more timer config options
Always-on local APIC timer (ARAT) has been introduced to Medfield, along
with the platform APB timers we have more timer configuration options
between Moorestown and Medfield.
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.
