Subject: [PATCH 5/6] cpufreq: Reuse gov_attr_* macros in schedutil governor

These macros can be used by governors which don't use the common
governor code present in cpufreq_governor.c and should be moved to the
relevant header.

Now that they are getting moved to the right header file, reuse them in
schedutil governor as well (that required rename of show/store
routines).
