x86: GART: Convert gart_iommu_hole_init() to use iommu_init hook
This changes gart_iommu_hole_init() to set gart_iommu_init() to iommu_init hook if gart_iommu_hole_init() finds the GART IOMMU. We can kill the code to check if we found the IOMMU in gart_iommu_init() since gart_iommu_hole_init() sets gart_iommu_init() only when it found the IOMMU.
