iommu: Remove apply_resv_region

The apply_resv_region callback in iommu_ops was introduced to reserve an
IOVA range in the given DMA domain when the IOMMU driver manages the IOVA
by itself. As all drivers converted to use dma-iommu in the core, there's
no driver using this anymore. Remove it to avoid dead code.
