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
