drm/amdgpu: DMA map/unmap when updating GPU mappings

Browse source

DMA map kfd_mem_attachments in update_gpuvm_pte. This function is called
with the BO and page tables reserved, so we can safely update the DMA
mapping.

DMA unmap when a BO is unmapped from a GPU and before updating mappings
in restore workers.
