gpu: host1x: Add IOMMU support2017-04-05T16:11:43ZMikko Perttunenmperttunen@nvidia.com2016-12-14T11:16:14Zurn:sha1:404bfb78daf3bedafb0bfab24947059575cbea3d
Add support for the Host1x unit to be located behind
an IOMMU. This is required when gather buffers may be
allocated non-contiguously in physical memory, as can
be the case when TegraDRM is also using the IOMMU.

Use the u32 type for the offset in the host1x_job_gather structure for
consistentcy with other structures. Negative offsets don't make sense in
this context.
