The number of words and the offset in a gather don't need to be
explicitly sized, so make them unsigned int instead.

Mikko Perttunen 404bfb78da gpu: host1x: Add IOMMU support
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.

Thierry Reding 3880e95f27 gpu: host1x: Make gather offsets unsigned
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.
