[1/2] cpufreq: Fix minor formatting issues

There were few noticeable formatting issues present in core cpufreq code. This
patch tries to fix them to make code look better. These are:
- Removing few extra blank lines
- Adding few blank lines
- replacing spaces with tabs
- removing unnecessary spaces
- rearranging code a bit
- Fixing multiline comments
- Break lines longer than 80 columns into multi-line.

At the end it also updates copyright information in cpufreq.c to include my name
for 2013.
