arm64: mediatek: Add Pinctrl/GPIO/EINT driver for mt8173.
Add mt8173 support using mediatek common pinctrl driver. MT8173 have a different ies_smt setting register than mt8135, so adding this support to common code. Signed-off-by: Hongzhou Yang <hongzhou.yang@mediatek.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
