FUJITA Tomonori ac7ded2adb x86: remove ifdef CONFIG_GART_IOMMU in pci-dma.c
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.
