I considered this before, however Cx is really a type, not a given state.
There can be more than 3 sleep states. For instance, the IBM R40 has C1,
C2, C3, and C3 (4 states). An index was the only unique way I could
specify the states. The transition latency is also unique but setting a
state to 182 to get the last C3 state is even worse from a user
perspective.
