google/veyron_emile: adjust to the spec of emile
o. Make some gpio changes base on Emile spec.
o. Init sdmmc function.
o. Revert cpu freq reducing in recovery mode since Emile
have more effective thermal than Mickey.
o. Revert the changes of lpddr3-samsung-2GB config.
BUG=chrome-os-partner:46658
TEST=build and boot on Emile
