pinctrl: mediatek: Fix fallback call path

Browse Source 
[ Upstream commit 81bd1579b4 ]

Some SoCs, eg. mt8183, are using a pinconfig operation bias_set_combo.
The fallback path in mtk_pinconf_adv_pull_set() should also try this
operation.

Fixes: cafe19db77 ("pinctrl: mediatek: Backward compatible to previous Mediatek's bias-pull usage")
