[Intel-gfx] [RFC 10/38] drm/i915: rename map/unmap to dma_map/unmap

[Michel Thierry]

From: Ben Widawsky <benjamin.widawsky at intel.com>

Upcoming patches will use the terms map and unmap in references to the
page table entries. Having this distinction will really help with code
clarity at that point.
