[PATCH v3 0/2] add support to STM HTS221 humidity + temperature sensor

Changes since v2:
- fix endianness issue in hts221_parse_caldata()
- make dev->buffer large enough to avoid the memcpy() in
  hts221_buffer_handler_thread()
- remove trigger top half routine and move timestamp sampling in
  hts221_buffer_handler_thread()
- use devm_iio_* routines to register iio_device/trigger and setup
  iio_triggered_buffer
- reduce spi max read/write size
- cosmetics

Changes since v1:
- use single iio_device for both humidity and temperature sensors
- use iio_claim_direct_mode() routine instead of grabbing the mutex directly
- use more unique prefix for all defines
- remove useless dev_info()
- use of_match_ptr instead of access directly to of_match_table
- use devm_iio_* routines
- use info_mask_shared_by_all element for sampling_frequency
- use oversampling ABI for humidityrelative_avg_sample and temp_avg_sample
