drm/ttm: Add DMA map/unmap tracepoint (v3)

Also exports two functions that vendor drivers can call
to trace DMA mappings.  This is meant to help translate
IOMMU mappings of bus addresses back to physical pages.

Used by the umr amdgpu debugger for instance.

(v2): Use dev_name() to get PCI path instead.
(v3): Use correct types for dma/phys addresses
