The thermal engine monitors the temperature readings from all sensors.
For each sensor, five threshold temperatures can be set:
1. Low fan speed.
2. High fan speed.
3. SMI warning.
4. Shutdown CPU.
5. Shutdown everything we can.
Each of these thresholds can be set to either a fixed value or disabled.
Currently the real implementation of SMI warning and shutting down is
left as TODO, as indicated in the comment.

This loosely ports the LM4 keyboard_scan code to STM32
Notable differences:
- Keyboard GPIO layout is spread across multiple ports and is not
contiguous in many places. Because of this, bitmasks are mostly
generated on-the-fly instead of hard coded (IO is kept to a minimum)
- Longer timeout when scanning columns (100us versus 20us)
Also, some functions are stubbed out currently since they rely on
other bits being implemented:
- keyboard_state_changed()
- keyboard_has_char()
- keyboard_put_char()
BUG=none
TEST=Tested on STM32L-Discovery (monitoring keystrokes via UART)
