[Lee Jones <lee.jones@linaro.org>]

Fixes the following W=1 kernel build warning(s):

  drivers/gpu/drm/radeon/radeon_legacy_encoders.c:1745:1: warning: no previous prototype for ‘radeon_add_legacy_encoder’ [-Wmissing-prototypes]
 1745 | radeon_add_legacy_encoder(struct drm_device *dev, uint32_t encoder_enum, uint32_t supported_device)
 | ^~~~~~~~~~~~~~~~~~~~~~~~~
