[PATCH 06/13] tools/power turbostat: Cleanup print helper functions

[Len Brown <lenb@kernel.org>]

From: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>

Make printer helper functions more readable by factoring
out a local 'sep' variable.

Remove the redundant parentheses around sprintf() calls.

Remove an unnecessary cast to "unsigned int" by using the '%08llx' instead
   of '%08x'.

No functional changes.

[lenb: fix typos, simplify]
