iommu/dma: use iommu_put_pages_list() to releae freelist

Free the IOMMU page tables via iommu_put_pages_list(). The page tables
were allocated via iommu_alloc_* functions in architecture specific
places, but are released in dma-iommu if the freelist is gathered during
map/unmap operations into iommu_iotlb_gather data structure.

Currently, only iommu/intel that does that.
