[PATCH 01/38] tick: align to Coding Guidelines

[Viresh Kumar <viresh.kumar@linaro.org>]

This does some trivial fixups:
- breaking lines longer than 80 columns
- merging few lines together
- don't break print messages even if they cross 80 columns
- remove few whitespaces
- remove few extra blank lines
