iommu/amd: Fix up merge conflict resolution

[ Upstream commit 8ec4e2befef10c7679cd59251956a428e783c0b5 ]

Merge commit e17c6debd4b2 ("Merge branches 'arm/mediatek', 'arm/msm', 'arm/renesas', 'arm/rockchip', 'arm/smmu', 'x86/vt-d' and 'x86/amd' into next")
added amd_iommu_init_devices, amd_iommu_uninit_devices,
and amd_iommu_init_notifier back to drivers/iommu/amd/amd_iommu.h.
The only references to them are here, so clean them up.

Fixes: e17c6debd4b2 ("Merge branches 'arm/mediatek', 'arm/msm', 'arm/renesas', 'arm/rockchip', 'arm/smmu', 'x86/vt-d' and 'x86/amd' into next")
