thermal: intel: intel_soc_dts_iosf: Utilize for_each_set_clump8 macro

Browse Source 
Utilize for_each_set_clump8 macro, and the bitmap_set_value8 and
bitmap_get_value8 functions, where appropriate.  In addition, remove the
now unnecessary temp_mask and temp_shift members of the
intel_soc_dts_sensor_entry structure.
