Convert the NVIDIA Legacy interrupt controller binding to schema format. It's a straight-forward conversion of the typical interrupt controller. All the possible compatibles were not documented, so add the ones in use.

All Tegra SoCs contain a legacy interrupt controller that routes interrupts to
|
|
the GIC, and also serves as a wakeup source. It is also referred to as
|
|
"ictlr", hence the name of the binding.
|
|
|
|
The HW block exposes a number of interrupt controllers, each implementing a
|
|
set of 32 interrupts.
|
|
|
|
Notes:
|
|
- Because this HW ultimately routes interrupts to the GIC, the
|
|
interrupt specifier must be that of the GIC.
|
|
- Only SPIs can use the ictlr as an interrupt parent. SGIs and PPIs
|
|
are explicitly forbidden.
