[Intel-gfx] [PATCH] drm/i915: update src and dst scaler limits for display ver 12 and 13

[Luca Coelho]

The bspec has been updated and now display versions 12 and 13 support
source width up to 5120 pixels, source height up to 8192 lines,
destination width up to 8192 and destination height up to 8192.

Update the code accordingly.
