[Intel-gfx] [PATCH v4 0/4] Do not access i915_gem_object members from frontbuffer tracking

["Jouni Högander" <jouni.hogander@intel.com>]

We are preparing for Xe driver. Binary objects will have differing
implementation in Xe driver. Due this we want to remove direct
accesses to i915_gem_object members and leave details to binary object
implementation.
