google/gru: change the sd power sequence
In the safety considerations, we should make sure the slot of SD is
enabled first, since we want to the power switch of corresponding is
powered up.
The different boards have the different power switch for sdmmc.
Some power switch IC need turn on delay for long time.
let's move the slot power of SD to romstage and avoid explicit delays
or per-board.
BRANCH=none
BUG=b:35813418, b:35573103
TEST=check the signal for children of gru, and boot up from sd card.
