prefetchw() requires it to be defined by linux/prefetch.h, or it results
in a compile error:

In file included from drivers/parisc/sba_iommu.c:916:0:
drivers/parisc/iommu-helpers.h: In function 'iommu_fill_pdir':
drivers/parisc/iommu-helpers.h:62:4: error: implicit declaration of function 'prefetchw'

Include linux/prefetch.h.
