The previous implementation was using a for loop. By it's
very definition the last statement in the for loop declaration
is done at the end of the loop. Therefore, if the conditional for
breaking out of the for loop because of a timeout would always
see a value of 0 for the number of APs accepted. Correct this
by changing to a while loop with an explicit timeout condition
at the end of the loop.

There are many good reasons why we may want to run some sort of generic
callback before we're executing a reset. Unfortunateley, that is really
hard right now: code that wants to reset simply calls the hard_reset()
function (or one of its ill-differentiated cousins) which is directly
implemented by a myriad of different mainboards, northbridges, SoCs,
etc. More recent x86 SoCs have tried to solve the problem in their own
little corner of soc/intel/common, but it's really something that would
benefit all of coreboot.
This patch expands the concept onto all boards: hard_reset() and friends
get implemented in a generic location where they can run hooks before
calling the platform-specific implementation that is now called
do_hard_reset(). The existing Intel reset_prepare() gets generalized as
soc_reset_prepare() (and other hooks for arch, mainboard, etc. can now
easily be added later if necessary). We will also use this central point
to ensure all platforms flush their cache before reset, which is
generally useful for all cases where we're trying to persist information
in RAM across reboots (like the new persistent CBMEM console does).
Also remove cpu_reset() completely since it's not used anywhere and
doesn't seem very useful compared to the others.

If an MTRR solution exceeds the number of available MTRRs
don't attempt to commit the result. It will just GP fault
with the MSR write to an invalid MSR address.
