drm/i915/gt: Rename dev_priv to i915 for private data naming consistency

It has become common practice to refer to the drm_i915_private
structures as "i915". However, there are still instances where
they are referred to as "dev_priv". This inconsistency can make
grepping for information more difficult and does not maintain a
cohesive style throughout the code.

Rename all the "dev_priv" structures in the gt/* directory to
"i915".
