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.

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.

The Tegra30 GPIO controller has one more bank than Tegra20, and hence
has one more interrupt.
