Subject: [PATCH net-next 1/3] dpaa2-eth: move the mqprio setup into a separate function

Move the setup done for MQPRIO into a separate function so that
with the addition of another offload we do not crowd
dpaa2_eth_setup_tc(). After this restructuring it's easier to see what
is supported in terms of Qdisc offloading.
