vt8500: multiplatform for 3.8

I just took a cursory look over the work required for enabling
multiplatform support for v3.8 for arch-vt8500.

There are 2 files I don't know what to do with in

1) entry-macro.S
Contains some low-level irq macro's.

2) irqs.h
Only contains '#define NR_IRQS 128' so I thought it would be easy enough
to get rid of, but it looks like I need to enable SPARSE_IRQ to drop it,
which will require some coding - what exactly is SPARSE_IRQ and what's
required to make it work?
