mainboard/intel/galileo: Add SD controller configuration

Configure the SD controller to handle the SD card slot.
* Galileo supports a removable SD card slot.
* Set SD card initialization frequency to 100 MHz.
* Set default removable delays.
* Build SD/MMC components by default

TEST=Build and run on Galileo Gen2
