Pull hwmon updates from Guenter Roeck:
 "Introduce new hwmon API functions hwmon_device_register_with_groups
  and devm_hwmon_device_register_with_groups, and convert several
  drivers to use the new API.

  Add support for EMC1404, EMC1424, LTC2977, LTC2978A, LM25063 to
  existing drivers

  Various cleanups in several drivers"
