cxgb4: add ETHOFLD hardware queue support
Add support for configuring and managing ETHOFLD hardware queues.
Keep the queue count and MSI-X allocation scheme same as NIC queues.
ETHOFLD hardware queues are dynamically allocated/destroyed as
TC-MQPRIO Qdisc offload is enabled/disabled on the corresponding
interface, respectively.
