R. A. Prado <nfraprado@xxxxxxxxxxxxx> commit b52e695324bb44728053a414f17d25a5959ecb9d upstream. 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. Since there aren't any users of mediatek,drive-strength-adv on mt8192 yet, remove this property and add drive-strength-microamp in its place, which has a clearer meaning.
