All the machines using the MMCI are passing GPIOs for the card detect and write protect using the device tree or descriptor table (one single case, Integrator/AP IM-PD1). Drop support for passing global GPIO numbers through platform data, noone is using it. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
