drm/xe/bmg: Update Wa_14022085890
Set GT min frequency to 1200Mhz once driver load is complete. v2: Review comments (Rodrigo) v3: Apply Wa earlier so user_req_min is not clobbered. v4: Apply to all GTs (Lucas) Cc: Matt Roper <matthew.d.roper@intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Vinay Belgaumkar <vinay.belgaumkar@intel.com> Reviewed-by: Stuart Summers <stuart.summers@intel.com> Link: https://lore.kernel.org/r/20250612-wa-14022085890-v4-3-94ba5dcc1e30@intel.com Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com>
