Subject: [PATCH 2/3] pinctrl: s32cc: configure PIN_CONFIG_DRIVE_PUSH_PULL

Previously, it was possible to only configure the open-drain for a pin.
However, after a pin got configured with open-drain, there wasn't any
way to disable it. Add the push-pull configuration in order to reverse
the open-drain configuration.
