[Uboot-stm32] [PATCH 07/36] dm: ofnode: fix parse_phandle_with_args API

[Casey Connolly]

When not using livetree, fdtdec_parse_phandle_with_args() is used both
to parse as well as to count the number of arguments. This means it
returns a positive integer in some cased (based on the index) which is
NOT valid for ofnode_parse_phandle_with_args().

Fix this by ignoring positive return value since it still indicates that
the phandle was parsed correctly.
