drm/amdgpu: rework reserved VMID handling
...
Instead of reserving a VMID for a single process allow that many
processes use the reserved ID. This allows for proper isolation
between the processes.

drm, iommu: Change type of pasid to u32
...
PASID is defined as a few different types in iommu including "int",
"u32", and "unsigned int". To be consistent and to match with uapi
definitions, define PASID and its variations (e.g. max PASID) as "u32".
"u32" is also shorter and a little more explicit than "unsigned int".
No PASID type change in uapi although it defines PASID as __u64 in
some places.
