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

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

this context.
