samples: Add sample app for MCP9808 sensor The app simply reads the temperature from the connected MCP9808 sensor. It forces -O0 compile flags, as the default (-Os) triggers a compiler bug when converting temperature readings.

sensor: Add threshold trigger support for MCP9808 The MCP9808 supports threshold triggering. Add support for this feature in the driver and the sample application. If triggering is activated, the driver can create its own fiber or use the system-wide sensor fiber.

drivers: sensor: mcp9808: fix various problems and improve test Correct handling of device encoded temperature values, which combine a 12-bit 2s complement signed value with a separate sign bit. Rework conversion between device and sensor temperature representations to support negative temperatures in both domains. Use a much simpler trigger configuration where the alert is driven by comparator output, rather than as an interrupt that requires a pair of I2C transactions to read and clear the flag. Refactor the trigger infrastructure to use the setup/handle/process idiom, which reduces duplicated code and to correctly detect alerts present when the triggers are set. Completely replace the sample with something that demonstrates updating upper and lower threshold values to track moving temperatures. Signed-off-by: Peter A. Bigot <pab@pabigot.com>
