- for_each_thermal_trip was added in 6.9, backport it for kernel
  versions that are < 6.9.0 and >= 6.0.0. Kernel versions < 6.0.0
  have the trips internal to the thermal core, so no access to it, on
  the other hand, the local (driver allocated) trips have invalid
  temperature values anyway, so no point iterating those trips,
  so added an empty backport for these kernels.
- struct thermal_trip has a few new fields, add these fields and extend
  the 6.0.0 to 6.9.0
- thermal_zone_device_register_with_trips is no longer supporting the
  mask argument, instead we have:
- THERMAL_TRIP_FLAG_RW_TEMP as a flag of a thermal_trip
