pinctrl: mediatek: fix build error

Due to pinconf_generic_parse_dt_config() API changes in pinctrl
devel branch, add one parameter to fix build error.

Also fix warning:
drivers/pinctrl/mediatek/pinctrl-mtk-common.c:718:3: warning:
too many arguments for format [-Wformat-extra-args]
      dev_err(&pdev->dev, "only support pins-are-numbered format\n", ret);
      ^

by removing extra parameter when calling dev_err in mtk_pctrl_init.
