[Intel-gfx] [PATCH] drm/i915/opregion: add missing intel_opregion_cleanup() dummy

[Arnd Bergmann]

From: Arnd Bergmann <arnd at arndb.de>

When ACPI is disabled, i915 fails to build because of a missing
declaration:

drivers/gpu/drm/i915/i915_driver.c: In function 'i915_driver_hw_probe':
drivers/gpu/drm/i915/i915_driver.c:556:9: error: implicit declaration of function 'intel_opregion_cleanup'; did you mean 'intel_opregion_setup'? [-Werror=implicit-function-declaration]
  556 |         intel_opregion_cleanup(dev_priv);

Add another empty dummy helper next to intel_opregion_setup().

Fixes: 3e226e4a2180 ("drm/i915/opregion: Cleanup opregion after errors during driver loading")
