pinctrl: mediatek: common-v1: Commonize spec_ies_smt_set callback

All of the MediaTek pinctrl drivers registering with pinctrl-mtk-common
that are offering a .spec_ies_smt_set() callback are declaring their
own function which is doing exactly the same on all drivers: calling
mtk_pconf_spec_set_ies_smt_range() with their struct and a simple check.

Commonize this callback by adding the ies and smt structure pointers
to struct mtk_pinctrl_devdata and changing the callback signature to
take it.

Removing the callback and checking for the existance of the spec_smt
and/or spec_ies data would allow us to staticize the function
mtk_pconf_spec_set_ies_smt_range(), but this solution was avoided as
to keep flexibility, as some SoCs may need to perform a very different
operation compared to what this commonized function is doing.
