arm: mach-snapdragon: gpio: introduce msm_special_pin_data
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.
