arm/tegra: convert tegra20 to GIC devicetree binding
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.
