x86: Gart: fix breakage due to IOMMU initialization cleanup
This fixes the following breakage of the commit
75f1cdf1dda92cae037ec848ae63690d91913eac:
- 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().
