net: Add QoS offload support for sparx5

This patch series adds support for offloading QoS features with the tc
command suite, to the sparx5 switch. The new offloadable QoS features
introduced in this patch series are:

  - tc-mqprio for mapping traffic class to hardware queue. Queues are by
    default mapped 1:1  in hardware, as such the mqprio qdisc is used as
    an attachment point for qdiscs tbf and ets.

    $ tc qdisc add dev eth0 root handle 1:0 mqprio

  - tc-tbf for setting up shaping on scheduler elements of the HSCH
    (Hierarchical Scheduler) block. Shaping on either port output or
    queue output is supported.

    Port shaper: $ tc qdisc add dev eth0 root handle 1:0 tbf rate \
    10000000 burst 8192 limit 1m

    Queue shaper: $ tc qdisc replace dev eth0 parent 1:5 handle 2:0 tbf \
    rate 10000000 burst 8192 limit 1m

  - tc-ets for setting up strict and or bandwidth-sharing bands on one
    through eight priority queues.

    Configure a mix of strict and bw-sharing bands:
    $ tc qdisc add dev eth0 handle 1: root ets bands 8 strict 5 \
    quanta 1000 1000 1000 priomap 7 6 5 4 3 2 1 0
