Changes since V1:
 - Add two new fixes for issues found during code rewrite.
 - Reorder enum coretemp_attr_index to better represent the 
   relationship between each element and keep their value in ascending
   order. Suggested by Ashok.
 - Replace sensor_device_attribute with sensor_device_attribute.
   Suggested by Ashok.
 - Use a dynamic allocated array to save the per core temperature info
   instead of a list. Suggested by Guenter.
 - Simplify the logic for handling pkg temp_data and core temp_data
   and remove unused marcos.
