intel_idle: remove use and definition of MWAIT_MAX_NUM_CSTATES
Cosmetic only. Replace use of MWAIT_MAX_NUM_CSTATES with CPUIDLE_STATE_MAX. They are both 8, so this patch has no functional change. The reason to change is that intel_idle will soon be able to export more than the 8 "major" states supported by MWAIT. When we hit that limit, it is important to know where the limit comes from.
