From: Randy Dunlap <[email-masked]>

Fix build errors when ACPI is not enabled by adding function stubs:

../drivers/gpu/drm/i915/i915_drv.c: In function 'i915_drm_suspend':
../drivers/gpu/drm/i915/i915_drv.c:635:2: error: implicit declaration of function 'intel_opregion_unregister' [-Werror=implicit-function-declaration]
  intel_opregion_unregister(dev_priv);
../drivers/gpu/drm/i915/i915_drv.c: In function 'i915_drm_resume':
../drivers/gpu/drm/i915/i915_drv.c:798:2: error: implicit declaration of function 'intel_opregion_register' [-Werror=implicit-function-declaration]
  intel_opregion_register(dev_priv);
