lisa._assets.kmodules.lisa: Add thermal trace

- Temperures of up to 12 thermal zones are traced to ftrace by
  polling. The poll interval can be set by defining
  CONFIG_POLL_INTERVAL_MS during build, which defaults to 100 ms.
  It will be clamped to be between 1 and 5000 ms inclusive.

- Thermal zones are selected by defining CONFIG_THERMAL_ZONE_LIST
  with a comma-separated list of thermal zone types (the value of
  /sys/class/thermal/thermal_zoneX/type) during build, otherwise,
  LITTLE,MID,BIG is used.
