Subject: [PATCH] pinctrl: pinconf-generic: check error value EOPNOTSUPP

From: Peng Fan <peng.fan@....com>

The SCMI error value SCMI_ERR_SUPPORT maps to linux error value
'-EOPNOTSUPP', so when dump configs, need check the error value
EOPNOTSUPP, otherwise there will be log "ERROR READING CONFIG SETTING".
