octeontx2-pf: consider both Rx and Tx packet stats for adaptive interrupt coalescing
The current adaptive interrupt coalescing code updates only rx packet stats for dim algorithm. This patch also updates tx packet stats which will be useful when there is only tx traffic. Also moved configuring hardware adaptive interrupt setting to driver dim callback.
