pinctrl: mediatek: add mtk_pctrl_spec_pull_set_samereg common code
Several mediatek soc use similar pull setting procedure as mt8173,
the pupd enable and resistance setting are in the same register.
Add common code mtk_pctrl_spec_pull_set_samereg out of spec_pull_set
in mt8173 to handle this case, so future soc driver can use it.
