power: remove unused poll counter

Browse Source 
Following the previous fix, there is nothing using the ppi counter.

We can remove the related ppi_av array in struct priority_worker.
This allows us to also remove num_dequeue_pkts_prev and pc from
struct priority_worker since they are only used in conjunction
with the ppi_av array.
