The sound and DRM modules carry a dependency on audio-support and
video-support, which is what decides whether an image handles those
devices. The AUDIO_SUPPORT and DISPLAY_SUPPORT tokens beside them add a
second, per-SoC-family condition that a board cannot influence, and that
DISPLAY_SUPPORT is half derived from whatever kernel configuration was
copied into a target's fragment.
Drop the tokens from the module dependencies and from fbtest.
