Merge tag 'tegra-soc2' of git://git.kernel.org/pub/scm/linux/kernel/git/olof/tegra into tegra/soc2

From: Olof Johansson <olof@lixom.net>
Tegra 30 SMP support

I did this as a separate topic branch because it depends on both the
soc and the soc-drivers branch, so it brings both of those in as a base.

This branch contains work to enable SMP support on Tegra30 and reworks
some of the SMP bringup for T20 as well.

It also contains a device tree patch that builds on top of the SMP/clock
changes in the rest of the branch, so it made more sense to apply it
here than deal with the merge conflicts back and forth.
