pinctrl: mediatek: paris: Fix PIN_CONFIG_BIAS_* readback
When reading back pin bias settings, if the pin is not in the corresponding bias state, the function should return -EINVAL. Fix this in the mediatek-paris pinctrl library so that the read back state is not littered with bogus a "input bias disabled" combined with "pull up" or "pull down" states.
