Some buses need to set up their devices before they can be used. This setup may well be common to all buses in a particular uclass. Support a common pre-probe method for the uclass, called before any bus devices are probed. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
