From: Iker Perez del Palomar Sustatxa <iker.perez@xxxxxxxxxxxxxxx>
The new fields are included to prepare the driver for next patch. The
fields are:
* *resolutions: Stores all the supported resolutions by the device.
* num_sample_times: Stores the number of possible sample times.
* *sample_times: Stores all the possible sample times to be set.
* sample_set_masks: The set_masks for the possible sample times
* sample_clr_mask: Clear mask to set the default sample time.

Changes since v1:
- In the lm75_params structure documentation there have been the next changes:
- @num_sample_times description has been extended.
- @sample_times description has been extended.
- @sample_set_masks description has been extended.
- @resolutions description has been included.
