Tegra's LIC (Legacy Interrupt Controller) has been so far only
supported as a weird extension of the GIC, which is not exactly

The stacked irq domain framework fits this pretty well, and allows
the LIC code to be turned into a standalone irqchip. In the process,
make the driver DT aware, something that was sorely missing from
the mach-tegra implementation.

Saw a few checkpatch warnings as below: all of them seem minors.

As a matter of principle, I ignore what checkpatch says about the
length of lines of code. I trust my eyes more than the tool.
