Splitting up the i915_gem_gtt caused a build failure in some configurations:
drivers/gpu/drm/i915/gt/intel_ggtt.c: In function 'ggtt_restore_mappings': drivers/gpu/drm/i915/gt/intel_ggtt.c:1239:3: error: implicit declaration of function 'wbinvd_on_all_cpus'; did you mean 'wrmsr_on_cpus'? [-Werror=implicit-function-declaration] wbinvd_on_all_cpus(); ^~~~~~~~~~~~~~~~~~ wrmsr_on_cpus
Add the missing header file.
