pinctrl: mediatek: make MediaTek pinctrl v2 driver ready for buidling loadable module
In the future we want to be able to build the MediaTek pinctrl driver, based on paris, as kernel module. This patch allows pinctrl-paris.c, the external interrupt controller mtk-eint.c, and pinctrl-mtk-common-v2.c to be loadable as module.
