hwmon: (adm1025) Fix checkpatch issues

Fixed:
ERROR: do not use assignment in if condition
ERROR: space required after that ',' (ctx:VxV)
ERROR: spaces required around that '<' (ctx:VxV)
ERROR: spaces required around that '=' (ctx:VxV)
ERROR: trailing whitespace
WARNING: simple_strtol is obsolete, use kstrtol instead
WARNING: simple_strtoul is obsolete, use kstrtoul instead

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