Subject: [RFT] iommu/amd: use subsys_initcall() on amdv2 iommu
We need to ensure amd iommu v2 initializes before
driver uses such as drivers/gpu/drm/amd/amdkfd/kfd_module.c,
to do this make its init routine a subsys_initcall() which
ensures its load init is called first than modules when
built-in.

Can someone test if this patch enables both CONFIG_AMD_IOMMU_V2 and
CONFIG_HSA_AMD to be =y (built-in) without any conflicts ?
