[PATCH 11/23] drm/xe/xe3p: Enable L2 flush optimization feature

[Lucas De Marchi <lucas.demarchi@intel.com>]

From: Tejas Upadhyay <tejas.upadhyay@intel.com>

When set, the L2 flush optimization feature will control whether L2 is
in Persistent or Transient mode through monitoring of media activity.

To enable L2 flush optimization include new feature flag
GUC_CTL_ENABLE_L2FLUSH_OPT is used when media gt type is detected.
