Since the bias-pull-{up,down} properties already have defines associated thus being more descriptive and is more universal on MediaTek platforms, and given that there are no mediatek,pull-{up,down}-adv users on mt8192 yet, remove the custom adv properties in favor of the generic ones. Note that only mediatek,pull-up-adv was merged in the binding, but not its down counterpart.
