Add support for the Trusted Foundations secure-mode firmware, as found
on NVIDIA SHIELD. This allows Linux to run in non-secure mode on this
board; all previous Tegra support has assumed the kernel is running in
secure mode.
This branch is based on v3.13-rc1, and shouldn't cause any merge
conflicts.

ARM: tegra: Trusted Foundations firmware support
Add support for the Trusted Foundations secure-mode firmware, as found
on NVIDIA SHIELD. This allows Linux to run in non-secure mode on this
board; all previous Tegra support has assumed the kernel is running in

(The base TF support has been discussed back and forth a lot; for now
the most logical place for it seems to be under arch/arm, so we're adding
it here. We can move it out to a common location in the future if needed).

Trusted Foundations is a TrustZone-based secure monitor for ARM that

This patch adds initial basic support for Trusted Foundations using
the ARM firmware API. Current features are limited to the ability to
boot secondary processors.
Note: The API followed by Trusted Foundations does *not* follow the SMC
calling conventions. It has nothing to do with PSCI neither and is only
relevant to devices that use Trusted Foundations (like most Tegra-based
retail devices).

Since a s3c64xx based system is one of my primary development platforms
it'd be really helpful if I could merge this into both ASoC and SPI,
I've got some patches for ASoC ready to go converting to use dmaengine

This patch prepare the transition to common clk for sama5 dt boards by
replacing the timer init callback.
Clocks registration cannot be done in early init callback (as formerly done
by the old clk implementation) because it requires dynamic allocation
which is not ready yet during early init.
In the other hand, at91 clocks must be registered before
at91sam926x_pit_init is called because PIT (Periodic Interval Timer) driver
request the master clk (mck).
A new function (at91sama5_dt_timer_init) is created to fullfil these needs.
This function registers all at91 clks using the dt definition before
calling the PIT init function.
The device tree clock registration is enabled only if common clk is
selected. Else the old clk registration is been done during
at91_dt_initialize call.
