ARM: tegra: second round of device tree changes

This branch includes some late device tree changes for Tegra:

A property is added to Whistler's device tree to enable the PMIC to
act as the pm_power_off() implementation.

A number of new device tree are added for boards from Avionic Design.

ARM: tegra: device tree changes

This branch adds two main features to Tegra boards, simply by amending
device tree files: regulator support and the ability to turn off system
power when executing "shutdown".

As part of these changes, the board file for Cardhu is split into two
versions, since different revisions have different hardware in some
areas, especially related to regulators.

Merge tag 'msm-dt-for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/davidb/linux-msm into next/dt

From David Brown:

These patches migrate both the 8660 and 8960 targets on msm to be
devicetree only.  This also sets most of the frame in place necessary
to build both targets into the same image.

There's a couple of cleanups in here that are kept in this series
because they are intimately tied to the changes necessary to support
the devicetree conversions.

This branch contains changes needed to make omap2+
work properly with sparse IRQ. It also removes
dependencies to mach/hardware.h. These help moving
things towards ARM single zImage support.

This branch is based on a commit in tty-next

cleanup-omap-tags-for-v3.7 merged in to keep things
compiling and sort out some merge conflicts.

The timer code relies on #defines from mach/iomap.h, cpu_is_*()
checks, and a global irq #define. All this makes this file
impossible to compile in a mult-target build. Therefore, make a
sys_timer struct for each SoC so that machine descriptors can
reference the correct timer. Then go through and replace all the
defines with raw values that are passed to a common
initialization function.

This paves the way to adding DT support to this code as well as
allows us to compile this file on multiple targets at the same
time.

With 3.4 kernel the static iomappings can be shared with the ioremap
mappings. If ioremap is called with an address for which a static
mapping already exists, then that mapping should be used instead
of creating a new one.

However, the MT_DEVICE_NONSHARED flag prevents this. Hence, get rid
of this flag. Some targets (7X00) that require the static iomappings
to be NONSHARED use the MSM_DEVICE_TYPE and MSM_CHIP_DEVICE_TYPE macros.

8660 "SURF" development platform.  Since this development platform is
not widely available, and there is now a more available device "the
Dragonboard" based on the same core SOC, this change was dropped.

However, the DT code kept a lingering call to this FPGA init function.
