From Stepen Warren:
ARM: tegra: add Tegra114 SoC support

This pull request adds initial support for the Tegra114 SoC, which
integrates a quad-core ARM Cortex-A15 CPU. I'm proud to observe that we
posted the initial versions of these patches before the final official
announcement of this chip.

These patches are enough to boot with a UART-based console, support the
Dalmore and Pluto reference/evaluation boards, instantiate the GPIO and
pinctrl drivers, and enable a cpuidle state. As yet, no clocks or
storage devices are supported, but patches for those will follow shortly.

This pull request is based on (most of) the previous pull request with
tag tegra-for-3.9-soc-cpuidle, followed by a merge of the previous pull
request with tag tegra-for-3.9-scu-base-rework.

Remove/remove conflict in arch/arm/mach-tegra/platsmp.c. Leave the empty
stub function for now since removing it in the merge commit is confusing;
will be cleaned up in a separate commit.  # # It looks like you may be
