ARM: sun9i: smp: fix return code check of of_property_match_string

Browse source

[ Upstream commit 643fe70e7b ]

of_property_match_string returns an int; either an index from 0 or
greater if successful or negative on failure. Even it's very
unlikely that the DT CPU node contains multiple enable-methods
these checks should be fixed.

This patch was inspired by the work of Nick Desaulniers.
