Subject: [PATCH 1/2] pinctrl: mediatek: Add mtk_eint_pm_ops to common-v2

pinctrl variants that include pinctrl-mtk-common-v2.h (and not
pinctrl-mtk-common.h) also need to use mtk_eint_pm_ops to setup
wake mask properly, so copy over the pm_ops to v2.

It is not easy to merge the 2 copies (or move
mtk_eint_suspend/resume to mtk-eint.c), as we need to
dereference pctrl->eint, and struct mtk_pinctrl *pctl has a
different structure definition for v1 and v2.
