drm/i915/guc: Remove GUC_CTL_DEVICE_INFO parameter

It looks that GuC does not actively use GUC_CTL_DEVICE_INFO parameter where we are passing GT type and Core family values. Let's stop/remove setup of this parameter and remove related definitions. v2: (this time without squashed HAX) - New title and description - Remove also GUC_CORE_FAMILY_* definitions (Michel) v3: - The removed define GUC_CTL_DEVICE_INFO has been restored (Michel) - Updated description (Sagar) v4: rebase Signed-off-by: Piotr Piórkowski <piotr.piorkowski@intel.com> Cc: Sagar Arun Kamble <sagar.a.kamble@intel.com> Cc: Michał Winiarski <michal.winiarski@intel.com> Cc: John A Spotswood <john.a.spotswood@intel.com> Cc: Michal Wajdeczko <michal.wajdeczko@intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Michel Thierry <michel.thierry@intel.com> Acked-by: Michel Thierry <michel.thierry@intel.com> Reviewed-by: Sagar Arun Kamble <sagar.a.kamble@intel.com> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20180413085245.57206-1-piotr.piorkowski@intel.com
