pinctrl: rockchip: Add rv1108 recalculated iomux support
The pins from GPIO1A0 to GPIO1B1 are special, need to recalculate iomux. And the register offset is larger than the u8 range, so changed to u32. 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>
