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.

cherry-pick from Chromium, commit 8fbe1e7
On Braswell and Baytrail devices, by userland 'perf top',
observed demanding clocks on __vdso_clock_gettime() since
chromeos_3.18 kernel; besides, evaluated massive calling of
clock_gettime() cost, up to 700 ns in average.
It turns out that Linux kernel of map_vdso() first call of
remap_pfn_range() does not fall into reserve_pfn_range()
due to size parameter, instead it relies on lookup_memtype()
and potentially be failed to be identified as eligible RAM
resource because the function of pat_pagerange_is_ram() actually
walks through root's sibling.
Meanwhile, on current BSW (and BYT) firmware implementation
makes System RAM resources located on child leaf, combining all
of these factors makes the kernel treat the vvar page of vdso
as a uncached-minus one leading slow access in result.
This patch recollects TOLM accessing; as Aaron recalled some
core_msr_script turns off access to TOLM register, he suggests
to store tolm to avoid getting back a zero while setting acpi
nvs space.
