[PATCH 3/6] drm/radeon: remove unused declarations for radeon

[Gaosheng Cui]

radeon_combios_get_ext_tmds_info() has been removed since
commit fcec570b27a4 ("drm/radeon/kms: add support for
external tmds on legacy boards").

radeon_mst has been removed since
commit 01ad1d9c2888 ("drm/radeon: Drop legacy MST support").

r600_hdmi_acr() has been removed since
commit 64424d6e45ae ("radeon/audio: consolidate update_acr()
functions (v2)").

So remove the declarations for them from header file.
