drm/i915: Make i915_coherent_map_type GT-centric
Refactor i915_coherent_map_type to be GT-centric rather than
device-centric. Each GT may require different coherency
handling due to hardware workarounds.
Since the function now takes a GT instead of the i915, the function is
renamed and moved to the gt folder.
