[Intel-gfx] [PATCH v2 4/4] drm/i915: Invalidate the TLBs on each GT

[Jonathan Cavitt <jonathan.cavitt@intel.com>]

From: Chris Wilson <chris.p.wilson@intel.com>

With multi-GT devices, the object may have been bound on each GT and so
we need to invalidate the TLBs across all GT before releasing the pages
back to the system.
