[RFC 28/31] drm/i915: Save trip via top-level i915 in a few more places

[Tvrtko Ursulin <tvrtko.ursulin@linux.intel.com>]

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

For gt related operations it makes more logical sense to stay in the realm
of gt instead of dereferencing via driver i915.

This patch handles a few of the easy ones with work requiring more
refactoring still outstanding.
