Tegra30 has 1 extra legacy interrupt controller. Use the GIC ITLinesNumber
field to determine how many interrupt controllers we have and initialize
appropriately. Also make room for the extra tegra30 interrupts by moving
the GPIO IRQ base. This shouldn't affect existing code as it determines the
correct IRQ number for GPIOs using TEGRA_GPIO_TO_IRQ().

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.
