......................................................................

soc/intel/quark: Add SD/MMC test support

* Add SD/MMC function
* Build SD/MMC driver
* Add ramstage SD card testing
* Select SDHC_DEBUG and SDHC_TRACE
* Don't pass in clock frequencies
* Use ctrlr instead of mmc_ctrlr
* Don't pass platform_info
* Move removable into ctrlr->caps
* Pass in MmcMedia
* Switch to mmc_ctrlr
* Use split driver
* Remove typedefs
* Add SD test code to romstage
* Switch to use storage_setup_media

TEST=Build and run on Galileo Gen2
