[PATCH v4 8/8] driver core: Move 2 one line device finding APIs to header

[Zijun Hu <zijun_hu@xxxxxxxxxx>]

From: Zijun Hu <quic_zijuhu@xxxxxxxxxxx>

The following device finding APIs only have one line code in function body
device_find_child_by_name()
device_find_any_child()

Move them to header as static inline function.
