As was already done for MT8192 in commit b52e695324bb ("dt-bindings: pinctrl: mt8192: Add drive-strength-microamp"), replace the custom mediatek,drive-strength-adv property with the standardized pinconf 'drive-strength-microamp' one. Similarly to the mt8192 counterpart, there's no user of property 'mediatek,drive-strength-adv', hence removing it is safe.
