Our way to handle gart_* functions for CONFIG_GART_IOMMU and
!CONFIG_GART_IOMMU cases is inconsistent.
We have some dummy gart_* functions in !CONFIG_GART_IOMMU case and
also use ifdef CONFIG_GART_IOMMU tricks in pci-dma.c to call some
gart_* functions in only CONFIG_GART_IOMMU case.
This patch removes ifdef CONFIG_GART_IOMMU in pci-dma.c and always use
dummy gart_* functions in iommu.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.

Hmm, looks like it would be nice to have more cleanups of iommu.h and
gart.h.

This patch renames the include file asm-x86/iommu.h to asm-x86/gart.h to make
clear to which IOMMU implementation it belongs. The patch also adds "GART" to
the Kconfig line.

Move the headers to include/asm-x86 and fixup the
header install make rules
