SPARSE_IRQ is implied by ARCH_MULTIPLATFORM, so we will have to
use it once that gets enabled.
Your new irqchip driver already handles IRQ domains, so it will
work out of the box with SPARSE_IRQ, but you have to change the
reference to "NR_IRQS" into something else.
I've prototyped a patch series to enable ARCH_MULTIPLATFORM,
I hope you can start working from what I have and get it to run.
