stm32f0: Pinky: Fix power leak caused by SPI at startup

Seems like we were setting outputs too early during boot, sometimes causing a
power leak. SPI should only turn on power levels more active than S3, not on the
S5->S3 transition.

BUG=chrome-os-partner:32824
BRANCH=None
TEST=Pinky powers on, Scope VCC33_PMUIO and VCC33_IO, note that they're smooth
