energy: Tighter checking of levels for DFS systems

There are cases where users might by accident / intention specify less voltage
operating points thatn frequency points.  We consider one of these cases
special: giving only a single voltage to a voltage domain effectively renders
it as a static domain.  This patch adds additional logic in the auxiliary parts
of the functionality to handle these cases properly (simple driver asking for
N>1 operating levels, we should return the same voltage for all of them) and
adds error checking code in the voltage domain.
