mmc: mmci: Add DT bindings for signal direction
Some variants have support for indicating the bus signal directions, which currently are configured through platform data. Add corresponding DT bindings to enable us to move away from using the platform data. Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org> Reviewed-by: Linus Walleij <linus.walleij@linaro.org>
