msm: eva: Identify the actual number of silver cores available with target

Browse Source 
As PM QOS request needs to done for silver cores only for EVA and
number of silver cores would be different for different target so,
better to identify the actual number of available silver cores.
Added cpu_possible check to confirm if cpu is available or not.
