pinctrl: rockchip: add support for multiple bank types
There are Rockchip SoCs, namely the rk3188, that combine a set of regular banks with banks that need special handling for some settings. Therefore add the possibility for the driver to handle more than one bank type. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
