pinctrl: mediatek: common: Fix probe failure for devices without EINT 

Some pinctrl devices like mt6397 or mt6392 don't support EINT at all, but
the mtk_eint_init function is always called and returns -ENODEV, which
then bubbles up and causes probe failure.

To address this only call mtk_eint_init if EINT pins are present.

Tested on Xiaomi Mi Smart Clock x04g (mt6392).
