[PATCH 40/85] drivers: gpu: Mark function as static in r600_hdmi.c

[Rashika Kheria]

Mark function r600_audio_set_dto() as static in drm/radeon/r600_hdmi.c
because it is not used outside this file.

This eliminates the following warning in drm/radeon/r600_hdmi.c:
drivers/gpu/drm/radeon/r600_hdmi.c:253:6: warning: no previous prototype for 
?r600_audio_set_dto? [-Wmissing-prototypes]
