mmc: mmci: Drop support for pdata GPIO numbers
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>
