x86: clean up iommu.h and gart.h
This remove lots of duplications in iommu.h and gart.h. The end result of this patch is: - iommu.h is a header file for everyone related with IOMMUs. - gart.h is the private header file. Only pci-gart_64.c and its friends include it. Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Cc: fujita.tomonori@lab.ntt.co.jp Signed-off-by: Ingo Molnar <mingo@elte.hu>
