drm/amdgpu: fix set scaling mode Full/Full aspect/Center not works on vga and dvi connectors
amdgpu_connector_vga_get_modes missed function amdgpu_get_native_mode which assign amdgpu_encoder->native_mode with *preferred_mode result in amdgpu_encoder->native_mode.clock always be 0. That will cause amdgpu_connector_set_property returned early on: if ((rmx_type != DRM_MODE_SCALE_NONE) && (amdgpu_encoder->native_mode.clock == 0)) when we try to set scaling mode Full/Full aspect/Center. Add the missing function to amdgpu_connector_vga_get_mode can fix this. It also works on dvi connectors because amdgpu_connector_dvi_helper_funcs.get_mode use the same method.
