cpuidle: governors: qcom-lpm: Do not disable CPUidle during suspend

Browse Source 
CPUidle was disabled during suspend to avoid runtime PM not updating
the cluster genpd sd counter post late suspend phase.

The issue is now fixed with commit a2bd7be12b ("PM: sleep: Fix runtime
PM based cpuidle support").

Remove the changes so CPU idle states can be allowed post late suspend
stage.
