hwmon: (lm85) Fix checkpatch issues 

Fixed:
ERROR: code indent should use tabs where possible
ERROR: do not use assignment in if condition
WARNING: simple_strtol is obsolete, use kstrtol instead
WARNING: simple_strtoul is obsolete, use kstrtoul instead

Modify multi-line comments to follow Documentation/CodingStyle.

Also: s/#define^I/#define /

Not fixed (false positive):
ERROR: Macros with multiple statements should be enclosed in a do - while loop
