x86, mrst: make mrst_timer_options an enum
...
We have an enum mrst_timer_options, use it so that the kernel knows if
we're missing something from a switch statement or equivalent.

x86, mrst: make mrst_identify_cpu() an inline returning enum
...
We have an enum, might as well use it. While we're at it, make it an
inline... there is really no point in calling a function for this
stuff.

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.

x86, mrst: add cpu type detection
...
Medfield is the follow-up of Moorestown, it is treated under the same
HW sub-architecture. However, we do need to know the CPU type in order
for some of the driver to act accordingly.
We also have different optimal clock configuration for each CPU type.
