Subject[PATCH 1/4] fbdev: make fb_find_mode look for a mode with the highest refresh rate
If the refresh rate hasn't been explicitly specified, fd_find_mode
currently returns the first mode with the requested resolution. Change
it so that it returns a mode with the requested resolution and the
highest refresh rate.

Also export fb_destroy_modelist, which is used in uvesafb.
