dt-bindings: pinctrl: mediatek: deprecate custom drive strength property

Deprecate mediatek,drive-strength-adv which shall not exist, that was an
unnecessary property that leaked upstream from downstream kernels and
there's no reason to use it.

The generic property drive-strength-microamp should be used instead.
