hwmon: (lm75) Add new fields into lm75_params_ 



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.
