The old setup function drm_fbdev_ttm_setup() is unused. Remove it and
its internal callbacks. New drivers should call drm_client_setup()
instead.

- * drm_fbdev_ttm_setup() - Setup fbdev emulation for TTM-based drivers
- * @dev: DRM device
- * @preferred_bpp: Preferred bits per pixel for the device.
- *
- * This function sets up fbdev emulation for TTM-based drivers that support
- * dumb buffers with a virtual address and that can be mmap'ed.
- * drm_fbdev_ttm_setup() shall be called after the DRM driver registered
- * the new DRM device with drm_dev_register().
- *
- * Restore, hotplug events and teardown are all taken care of. Drivers that do
- * suspend/resume need to call drm_fb_helper_set_suspend_unlocked() themselves.
- * Simple drivers might use drm_mode_config_helper_suspend().
- *
- * In order to provide fixed mmap-able memory ranges, fbdev emulation
- * uses a shadow buffer in system memory. The implementation blits the shadow
- * fbdev buffer onto the real buffer in regular intervals.
- *
- * This function is safe to call even when there are no connectors present.
- * Setup will be retried on the next hotplug event.
- *
- * The fbdev is destroyed by drm_dev_unregister().
