Subject: [PATCH] drm/i915: add intel_opregion_vbt_present() stub function

From: Arnd Bergmann <arnd@...db.de>

The newly added function is not available without CONFIG_ACPI, causing
a build failure:

drivers/gpu/drm/i915/display/intel_bios.c:3424:24: error: implicit declaration of function 'intel_opregion_vbt_present'; did you mean 'intel_opregion_asle_present'? [-Werror=implicit-function-declaration]

Add an empty stub in the same place as the other stubs.

Fixes: 9d9bb71f3e11 ("drm/i915: Extract opregion vbt presence check")
