This series removes the include of mach/irqs.h from asm/irq.h when
SPARSE_IRQ is selected. Platforms which select SPARSE_IRQ have been
updated.

This breaks platforms where SPARSE_IRQ is user selectable. This is on
purpose so that SPARSE_IRQ gets properly supported. We could push
HAVE_SPARSE_IRQ option down to the platforms that select it if that is
preferred. But as recent experience has shown, perhaps breaking platforms
is the only way to get some platforms updated.

Nice one Rob!  Patch below to remove irqs.h for picoxcell too if you 
could add that one to your series.

Subject: [PATCH] ARM: picoxcell: remove mach/irqs.h

picoxcell uses SPARSE_IRQ which means we don't need a mach/irqs.h
anymore so kill it off.
