pinctrl: rockchip: Add iomux-route switching support for rk3328
There are 8 IP blocks pin routes need to be switched, that are uart2dbg, gmac-m1-optimized, pdm, spi, i2s2, card, tsp, cif. Signed-off-by: David Wu <david.wu@rock-chips.com> Reviewed-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
