mmc: host: sdhci: update pm qos votes based on cpu clusters

Performance of the workload largely depends on the pm qos votes.
Dynamically identify the core in which the current task is running
and apply the pm qos votes to the cluster that this core belongs to.
This ensures that the performance of the workload is not impacted and
also improves the power efficiency of the system.
