[OSS-Tools] [PATCH 2/5] libdt: fix issues of external function without prototype

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

When increasing warning level, we see that of_find_device_by_node_path
lacks a prototype despite having external linkage and being exported
in the symbols file. On the other hand, scan_proc_dir has external
linkage, but is only ever needed internally, so let's give it internal
linkage.
