stm32: drive the keyboard power LED
Put the power LED in the right state (off, on, breathing) depending on
the AP state (off, running, suspending).
The power LED is connected to GPIO B3.
The AP suspend detection is done through GPIO A7.
(so we no longer configure it as SPI alternate function)

BUG=chrome-os-partner:10647
TEST=on Lucas DVT, boot/stop the board and see the LED on and off.
