mmc: jz4740: Let the pinctrl driver configure the pins
Now that the JZ4740 and similar SoCs have a pinctrl driver, we rely on the pins being properly configured before the driver probes. Signed-off-by: Paul Cercueil <paul@crapouillou.net> Acked-by: Ulf Hansson <ulf.hansson@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
