iommu: msm: move msm_iommu_register_notify 



It's currently inside an `#ifdef CONFIG_MSM_IOMMU_VBIF_CHECK', which is
incorrect since it doesn't actually depend on that config.  Drivers that
want to use it fail to link when CONFIG_MSM_IOMMU_V1=y &&
CONFIG_MSM_IOMMU_VBIF_CHECK=n.  Move it out and export it while we're at
it.
