drm/i915: Add a new "remapped" gtt_view
To overcome display engine stride limits we'll want to remap the
pages in the GTT. To that end we need a new gtt_view type which
is just like the "rotated" type except not rotated.
v2: Use intel_remapped_plane_info base type
s/unused/unused_mbz/ (Chris)
Separate BUILD_BUG_ON()s (Chris)
Use I915_GTT_PAGE_SIZE (Chris)
v3: Use i915_gem_object_get_dma_address() (Chris)
Trim the sg (Tvrtko)
v4: Actually trim this time. Limit the max length
to one row of pages to keep things simple
