The GIC-400 driver currently only supports SPIs because the (32) offset for the INTIDs is hard-coded in the driver. At the driver level there is no really difference between PPIs and SPIs so we can easily extend the driver to support PPIs as well. This is useful if we want to add support for the ARM Generic Timers that use INTIDs in the PPI range. SPI interrupts are in the range [0-987]. PPI interrupts are in the range [0-15]. This commit adds interrupt 'type' cell to the GIC device tree binding and changes the 'irq' cell to use interrupt type-specific index, rather than a linear IRQ number. The 'type'+'irq (index)' combo is automatically fixed up into a linear IRQ number by the scripts/dts/gen_defines.py script.
