layerscape: reverse changes to ndo_get_stats64

The NXP LSDK kernel backported changes for interface ndo_get_stats64
functions from mainline, this causes a compile error with
backports/mac80211, which expects the original 4.9 defintion.

As reversing the ndo_get_stats64 change signifcantly reduces the size of
patch 601, the patches that were aggregated into it have been
disaggregated.

+Subject: [PATCH] sdk_dpaa: update the xmit timestamp to avoid watchdog
+ timeouts
+
+[core-linux part]
+
+Update txq0's trans_start in order to prevent the netdev watchdog from
+triggering too quickly. Since we set the LLTX flag, the stack won't update
+the jiffies for other tx queues. Prevent the watchdog from checking the
+other tx queues by adding the NETIF_HW_ACCEL_MQ flag.
