Enhance the driver to dynamically allocate the base IRQ number, and
create an IRQ domain for itself. The use of an IRQ domain ensures that
any device tree node interrupts properties are correctly parsed.

Describe interrupt-related properties in the device tree binding docs,
and the contents of "child" node interrupts property.

Update tegra*.dtsi to specify the required interrupt-related properties.

Finally, remove the definition of TEGRA_GPIO_TO_IRQ; this macro no longer
gives correct results since the IRQ numbers for GPIOs are dynamically
allocated.

The Tegra PMC (Power Management Controller) interfaces with an external
PMU (Power Management Unit), and controls wake-up from sleep modes.

This initial binding is the bare minimum required to control the PMC's
inversion of the PMU's interrupt signal.

Adjust the dma-channel property name to match the binding implemented by
the driver. The binding was implemented and documented in a
separate change to the ASoC tree.

Document binding, and add the node to tegra*.dtsi.

The driver isn't actually instantiated from this node yet, but the I2S
binding will rely on being able to refer to the APB DMA node using a
phandle.

Update the device tree to indicate which I2C controller is the DVC
controller. AUXDATA needs to be updated too, since the compatible

Convert tegra20 IRQ intialization to the GIC devicetree binding. Modify the
interrupt definitions in the dts files according to
Documentation/devicetree/bindings/arm/gic.txt

v3 (swarren):
* Moved of_irq_init() call into board-dt.c to avoid ifdef'ing it.
  - Even with a dummy replacement if !CONFIG_OF, the reference from
    tegra_dt_irq_match[] to gic_of_init() would still have to be ifdef'd
  - It's plausible that tegra_dt_irq_match[] may need to contain more
    entries in the future, and defining what they are seems more suitable
    for board-dt.c than irq.c
v2 (swarren):
* Removed some stale GIC init code from board-dt.c
* Undid some accidental 0x -> 0x0 search/replace.

Everything required to populate NVIDIA Tegra devices from the device
tree.  This patch adds a new DT_MACHINE_DESC() which matches against
a tegra20 device tree.  So far it only registers the on-chip devices,
but it will be refined in follow on patches to configure clocks and
pin IO from the device tree also.
