cpufreq: governor: Change confusing struct field and variable names
The name of the prev_cpu_wall field in struct cpu_dbs_info is
confusing, because it doesn't represent wall time, but the previous
update time as returned by get_cpu_idle_time() (that may be the
current value of jiffies_64 in some cases, for example).
Moreover, the names of some related variables in dbs_update() take
that confusion further.
Rename all of those things to make their names reflect the purpose
more accurately. While at it, drop unnecessary parens from one of
the updated expressions.
No functional changes.
