The only reason to have these functions on drm_framebuffer would be if they would added a abstraction layer to call it just passing a drm_framebuffer pointer and the desired plane index, which is not the case, where these functions actually implements just part of it. In the actual implementation, every call to both drm_framebuffer_plane_{width,height} and fb_plane_{width,height} should pass some drm_framebuffer attribute, which is the same as calling the drm_format_info_plane_{width,height} functions. The drm_format_info_pane_{width,height} functions are much more consistent in both its implementation and its location on code. The kind of calculation that they do is intrinsically derivated from the drm_format_info struct and has not to do with drm_framebuffer, except by the potential motivation described above, which is still not a good justificative to have drm_framebuffer functions to calculate it. So, replace each drm_framebuffer_plane_{width,height} and fb_plane_{width,height} call to drm_format_info_plane_{width,height} and remove them.
