hwmon: (dme1737) Fix checkpatch issues

Fixed:
WARNING: braces {} are not necessary for any arm of this statement
WARNING: braces {} are not necessary for single statement blocks
WARNING: simple_strtol is obsolete, use kstrtol instead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
