hwpstate: use CPU_FOREACH when binding to all available processors

Also, add a comment mentioning _PSD - on some systems it's enough to
put one logical CPU into a particular P-state to make other CPUs in
the same domain to enter that P-state.

Also, call sched_unbind() after the loop - sched_bind() automatically
rebinds from previous CPU to a new one, and the new arrangement of code
is safer against early loop exit.

Plus one minor style nit.
