stm32l: add a simple power sequencing for Daisy board
This should be enough to switch on the board from either the power
button or the EC console.
Signed-off-by: Vincent Palatin <vpalatin@chromium.org>
BUG=None
TEST=run Daisy firmware on Discovery board with logic analyzer attached
to GPIO pins. With an added task to simulate PMIC startup and AP
startup, check the timing chart looks good.
