These changes are all specific to an soc family or the code for
one soc. Lots of work for Tegra3 this time, but also a lot of other
platforms. There will be another (smaller) set of soc patches later in
the merge window for stuff that has dependencies on external trees or
that was sent just before the merge window opened.
The asoc tree added a few devices to the i.mx platform, which conflict
with other devices added in the same place here.
The tegra Makefile conflicts between a number of branches, mostly because
of changes regarding localtimer.c, which was removed in the end.

Add support for the new smp_twd runtime registration interface
to the highbank platforms, and remove the old compile-time support.
The highbank DTS file is updated to match the TWD DT documentation
and fixes the timer trigger (rising edge).

Merge tag 'v3.3-rc2' into depends/rmk/for-armsoc
There were conflicts between fixes going in after 3.3-rc1 and
Russell's stable arm-soc base branch. Resolving it in the dependency
branch so that each topic branch shares the same resolution.

It turns out that the logical CPU mapping is useful even when !CONFIG_SMP
for manipulation of devices like interrupt and power controllers when
running a UP kernel on a CPU other than 0. This can happen when kexecing
a UP image from an SMP kernel.
In the future, multi-cluster systems running AMP configurations will
require something similar for mapping cluster IDs, so it makes sense to
decouple this logic in preparation for this support.

Remove the now empty arch_reset() from all the mach/system.h includes,
and remove its callsite. Remove arm_machine_restart() as this function
no longer does anything useful.
For samsung platforms, remove the include of mach/system-reset.h and
plat/system-reset.h from their respective mach/system.h headers as these
just define their arch_reset functions. As a result, the s3c2410 and
plat-samsung system-reset.h files are no longer referenced, so remove
these files entirely.
