[PATCH 1/3] iommu/dma: Add some missing #includes

[Robin Murphy]

dma-iommu.c was naughtily relying on an implicit transitive #include of
linux/vmalloc.h, which is apparently not present on some architectures.
Add that, plus a couple more headers for other functions which are used
similarly.

Hi Joerg,

here are a couple more minor fixes for some obscure subtleties in the
common DMA code. I see I've just missed the rc5 fixes pull, but I hope
you can pick these up for rc6 (unless of course you're also just about
to disappear for 2 weeks like I am).

Thanks,
Robin.
