Move the armada_drm_mode_config_funcs to armada_drv.c, since this now has less to do with FBs than it does with general mode configuration. In doing so, we need to make armada_fb_create() visible to armada_drv.c, which reveals a function name clash with armada_fbdev.c. Rename the version in armada_fbdev.c.
