drm/gpusvm: Add devmem callback to get_pages
Add an optional drm_gpusvm_ctx.devmem_fn, invoked for each device-memory
allocation backing the range's faulted pages. It runs under the notifier
lock and independently of the DMA map, so it also fires with no_dma_map.
Adjacent pages of one allocation are coalesced, so the callback must be
idempotent.
v2
Reset last to NULL for non-devmem pages(Sashiko/Matt)
v3
Run drm_gpusvm_pages_valid_unlocked() on the map_dma path even when
devmem_fn is set, so an invalidated range's stale inline mapping is
reset.
