[Nouveau] [PATCH] drm/nouveau: Fix build error in nouveau_acpi.c

[Stratos Psomadakis]

From: Stratos Psomadakis <psomas at cslab.ece.ntua.gr>

Fix compilation failure when CONFIG_ACPI=y, but CONFIG_ACPI_VIDEO is not
selected by Kconfig (ie CONFIG_ACPI_VIDEO=m|n)

When CONFIG_ACPI_VIDEO != y, nouveau_acpi_edid will fail to build, due to the
call to the 'acpi_video_get_edid' function.
