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.
