drm/pagemap: Add DRM pagemap
Introduce drm_pagemap ops to map and unmap dma to VRAM resources. In the
local memory case it's a matter of merely providing an offset into the
device's physical address. For future p2p the map and unmap functions may
encode as needed.
Similar to how dma-buf works, let the memory provider (drm_pagemap) provide
the mapping functionality.
v3:
- Move to drm level include
v4:
- Fix kernel doc (G.G.)
v5:
- s/map_dma/device_map (Thomas)
- s/unmap_dma/device_unmap (Thomas)
v7:
- Fix kernel doc (CI, Auld)
- Drop P2P define (Thomas)
