This reverts commit b7cde7078d2344073c310aa65fc2b0a845d2cb5b
("mfd: sec-core: Prepare regulators for suspend state to reduce power-consumption")
Commit b7cde7078d23 called regulator_suspend_prepare() to prepare the
regulators for a suspend state. But did it from the device pm suspend
handler but regulator_suspend_prepare() iterates over all regulators
and not only the one managed by this device so it doesn't seems to be
correct to call it from a device driver.
It is better to call the regulator suspend prepare/finish functions
from platform code instead so this patch reverts the mentioned commit.
