sched/walt:Do not use package id while setting up clusters

Browse Source 
Currently, setting up WALT clusters requires using the physical package
id assigned to each core to identify which cluster the CPU belongs to.
However, due to upstream changes to the way clusters are parsed in the
devicetree, physical package id does not represent cluster information
anymore.
Switch to using cluster id from cpu topology to fix this.
