mfd: syscon: Support native-endian regmaps
The regmap devicetree binding documentation states that a native-endian property should be supported as well as big-endian & little-endian, however syscon in its duplication of the parsing of these properties omits support for native-endian. Fix this by setting REGMAP_ENDIAN_NATIVE when a native-endian property is found.
