pinctrl: renesas: rzg2l: Return -EINVAL if the pin doesn't support PIN_CFG_OEN
Update the rzg2l_pinctrl_pinconf_get() function to return -EINVAL for
PIN_CONFIG_OUTPUT_ENABLE config if the pin doesn't support the PIN_CFG_OEN
configuration.
-EINVAL is a valid error when dumping the pin configurations. Returning
-EOPNOTSUPP for a pin that does not support PIN_CFG_OEN resulted in the
message 'ERROR READING CONFIG SETTING 16' being printed during dumping
pinconf-pins.
For consistency do similar change in rzg2l_pinctrl_pinconf_set() for
PIN_CONFIG_OUTPUT_ENABLE config.
