Commit 106937e8ccdc ("of: fix handling of '/' in options for
of_find_node_by_path()") caused a regression in OF handling of
stdout-path. While it fixes some cases which have '/' after the ':', it
breaks cases where there is more than one '/' *before* the ':'.

For example, it breaks this boot string

  stdout-path = "/rdb/serial@f040ab00:115200";

So rather than doing sequentialized checks (first for '/', then for ':';
or vice versa), to get the correct behavior we need to check for the
first occurrence of either one of them.

It so happens that the handy strcspn() helper can do just that.
