veyron_danger: Update SDMMC power on/off code for v2

This re-factors SDMMC power on/off to make corrections and take
    differences between board versions into account. To avoid similar-
    but-different case switch statements in romstage.c and mainboard.c,
    power on/off functions for SDMMC are split into their own .c file.

BUG=none
    BRANCH=none
    TEST=built and booted of micro-SD card on Danger v2
