In order to help setup pin configuration for special pins (UFS, SDCard), introduce the msm_special_pin_data struct largely inspired from the Linux conterpart but with only U-Boot required fields. This struct is added to the pins_data to allow specifying the special pins data for each SoC. Signed-off-by: Neil Armstrong <neil.armstrong@linaro.org> Reviewed-by: Sumit Garg <sumit.garg@linaro.org>
