Subject: [PATCH v2 4/5] pinctrl: mediatek: common-v1: Commonize spec_pupd callback
Reduce code size and duplication by using a common spec_pupd callback,
which is possible to use on all of the pinctrl drivers that are
using the v1 pinctrl-mtk-common code, with the exception of mt8135,
which has a different handling compared to the others.
Since the callback function signature was changed, this had to be
propagated to pinctrl-mt8135's spec_pull_set().
