Yinghai Lu f3eee54276 x86: Gart: fix breakage due to IOMMU initialization cleanup 
This fixes the following breakage of the commit
75f1cdf1dd:

- GART systems that don't AGP with broken BIOS and more than 4GB
  memory are forced to use swiotlb. They can allocate aperture by
  hand and use GART.

- GART systems without GAP must disable GART on shutdown.

- swiotlb usage is forced by the boot option,
  gart_iommu_hole_init() is not called, so we disable GART
  early_gart_iommu_check().
