[PATCH] soc: samsung: Use syscon_regmap_lookup_by_phandle_args

[Krzysztof Kozlowski]

Use syscon_regmap_lookup_by_phandle_args() which is a wrapper over
syscon_regmap_lookup_by_phandle() combined with getting the syscon
argument.  Except simpler code this annotates within one line that given
phandle has arguments, so grepping for code would be easier.
