Commit cafe19db7751 ("pinctrl: mediatek: Backward compatible to previous
Mediatek's bias-pull usage") allowed the bias-pull-up and bias-pull-down
properties to be used for setting PUPD/R1/R0 type bias on mtk-paris
based SoC's, which was previously only supported by the custom
mediatek,pull-up-adv and mediatek,pull-down-adv properties.
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.
While at it, also add 'if' blocks to prevent bias-disable, bias-pull-up
and bias-pull-down to be used together, since they're mutually
exclusive.
