Commit e5fabbe43f3f ("pinctrl: mediatek: paris: Support generic PIN_CONFIG_DRIVE_STRENGTH_UA") added support for using drive-strength-microamp instead of mediatek,drive-strength-adv. Similarly to the mt8192 and mt8195, there's no user of property 'mediatek,drive-strength-adv', hence removing it is safe.
