The dma-map IOVA alloc, link, and sync APIs perform significantly better
than dma-map / dma-unmap, as they avoid costly IOMMU synchronizations.
This difference is especially noticeable when mapping a 2MB region in
4KB pages.
Use dma-map IOVA alloc, link, and sync APIs for GPU SVM and DRM page,
which mappings between the CPU and GPU.
Initial results are promising.

All current users of DRM pagemap set source_peer_migrates to true during
migration, and it is unclear whether any user would ever want to disable
this for performance reasons or for features such as compression. It is
also questionable whether this flag could be made to work with
high-speed fabric mapping APIs.
Drop the flag and make DRM pagemap unconditionally assume that
source_peer_migrates is true.

Split drm_pagemap_migrate_map_pages into device / system helpers clearly
seperating these operations. Will help with upcoming changes to split
IOVA allocation steps.

The dma-map IOVA alloc, link, and sync APIs perform significantly better
than dma-map / dma-unmap, as they avoid costly IOMMU synchronizations.
This difference is especially noticeable when mapping a 2MB region in
4KB pages.
Use the IOVA alloc, link, and sync APIs for DRM pagemap, which create DMA
mappings between the CPU and GPU for copying data.

Replace @dma_addr with @pagemap_addr in the function documentation,
as @pagemap_addr is the actual name of the function argument.
