====================
dpaa2-eth: misc cleanup

This patch set consists of some cleanup patches ranging from removing dead
code to fixing a minor issue in ethtool stats. Also, unbounded while loops
are removed from the driver by adding a maximum number of retries for DPIO
portal commands.

Changes in v2:
 - return -ETIMEDOUT where possible if the number of retries is hit
