Niklas Schnelle 657d42cf5d s390/ism: Set DMA coherent mask ...

A future change will convert the DMA API implementation from the
architecture specific arch/s390/pci/pci_dma.c to using the common code
drivers/iommu/dma-iommu.c which the utilizes the same IOMMU hardware
through the s390-iommu driver. Unlike the s390 specific DMA API this
requires devices to correctly set the coherent mask to be allowed to use
IOVAs >2^32 in dma_alloc_coherent(). This was however not done for ISM
devices. ISM requires such addresses since currently the DMA aperture
for PCI devices starts at 2^32 and all calls to dma_alloc_coherent()
would thus fail.
