cppc_cpufreq: fix misspelling, code style and readability issues

Fix a few trivial issues in the cppc_cpufreq driver:

 - indentation of function arguments
 - consistent use of tabs (vs space) in defines
 - spelling: s/Offest/Offset, s/trasition/transition
 - order of local variables, from long pointers to structures to
   short ret and i (index) variables, to improve readability
