profiles: Correct CPU governor settings

First, always prefer schedutil for balanced/powersave. On platforms
where this governor is available, this enables Energy-Aware-Scheduling
which offers the best power efficiency and performance combination.
There is absolutely no reason to use another governor by default in the
"balanced" profile on these systems, in particular.

Second, swap around "conservative" and "ondemand". "conservative" is
supposed to be lower power and higher latency. The commit that made this
change tested on a single server platform (10 years ago), but unless
that governor is behaving opposite to what is documented on most
platforms, that was probably an outlier or a testing mistake.
