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.
