ACPI / video: mark acpi_video_get_levels() inline 

A recent patch added a stub function for acpi_video_get_levels when
CONFIG_ACPI_VIDEO is disabled. However, this is marked as 'static'
and causes a warning about an unused function whereever the header
gets included:

In file included from ../drivers/gpu/drm/radeon/radeon_acpi.c:28:0:
include/acpi/video.h:74:12: error: 'acpi_video_get_levels' defined but not used [-Werror=unused-function]

This makes the declaration 'static inline', which gets rid of the
warning.
