ACPI: Reintroduce run time configurable max_cstate for !CPU_IDLE case

This was writeable in 2.6.23 but the cpuidle merge made it read-only.  But
some people's scripts (ie: Mark's) were writing to it.

As an unhappy compromise, make max_cstate writeable again if the kernel was
configured without CONFIG_CPU_IDLE.
