OMAP3: cpuidle: Add valid field into C-state parameter passing
Different boards benefit differently from the available seven C-states for cpu idle. In most cases, only few, properly spaced (in terms of consumption and latency) C-states are required to make the power management optimal. Hence we need a possibility to pass which C-states are actually used for each board. So added the valid field to cpuidle_params and added support to 3430sdp, which uses the paramenter passing.
