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.

Ideally we'd prevent using drive-strength-microamp together with drive-strength,
like I intended to do on v2 of the patch [1], just as an extra sanity check. But
that could be added later on top, so

Now failing in linux-next. Looks like the example needs updating:
Documentation/devicetree/bindings/pinctrl/pinctrl-mt8195.example.dtb:
pinctrl@10005000: i2c0-pins:pins: 'mediatek,drive-strength-adv' does
not match any of the regexes: 'pinctrl-[0-9]+'
From schema: /builds/robherring/linux-dt/Documentation/devicetree/bindings/pinctrl/pinctrl-mt8195.yaml
