Support for ARM Ltd. Integrator systems depends on ARCH_MULTIPLATFORM.
As the latter selects SPARSE_IRQ, there is no need for ARCH_INTEGRATOR
to select SPARSE_IRQ.

The patch shifting the IRQ-numbering by one is a prerequisite for the two
above patches, right?

I only remember sending two patches for ep93xx:
ARM: ep93xx: make mach/ep93xx-regs.h local
ARM: ep93xx: enable SPARSE_IRQ
and have added the Tested-by tag to them now. Is there a third one
I missed?

Everything is in place now for SPARSE_IRQ. Select it and set
DAVINCI_INTC_START to NR_IRQS.
We now need to include mach/irqs.h in a couple places as it is no
longer indirectly included after selecting SPARSE_IRQ.

This is done in preparation for selecting CONFIG_SPARSE_IRQ. The
interrupt numbers will then start at the predefined NR_IRQS offset.
For now wrap all interrupt numbers with a macro and define
DAVINCI_INTC_START to 0.

For now wrap all interrupt numbers with a macro and define
