iommu: Delete iommu_dma_free_cpu_cached_iovas() 

ANBZ: #1704

commit 149448b353 upstream.

Function iommu_dma_free_cpu_cached_iovas() no longer has any caller, so
delete it.

With that, function free_cpu_cached_iovas() may be made static.

Intel-SIG: commit 149448b353 iommu: Delete iommu_dma_free_cpu_cached_iovas().
