drm/amd/amdgpu: Add tracepoint for DMA page mapping (v4)
This helps map DMA addresses back to physical addresses.

(v2): Added tracepoints for USERPTR, SG mappings, and
SWIOTBL mappings. Reformatted trace call perform
PCI decoding internal to the trace.
(v3): Add unmap tracepoints as well
(v4): Move traces into separate functions
