of: Drop properties with "/" in their name

Some bogus firmwares include properties with "/" in their name. This
causes problems when creating the /proc/device-tree file system,
because the slash is taken to indicate a directory.

We don't care about those properties, and we don't want to encourage
them, so just throw them away when creating /proc/device-tree.
