[PATCH 1/2] drm/xe/vf: Read VF configuration prior to GGTT initialization

[Michal Wajdeczko <michal.wajdeczko@intel.com>]

Each VF will be assigned with only a limited range of the GGTT
address space. Make sure that VF driver will read its own GGTT
configuration before starting any GGTT initialization.
