net/cxgbe: rework and use 32-bit port capability

The new code uses the new 32-bit Port Capabilities exclusively and
only translates to/from the old 16-bit Port Capabilities at the last
point possible when talking to older Firmware.

For the old versus new Firmware issue, we use the new FW_PARAMS_CMD[PFVF,
CAPS32] command to tell the Firmware that we want Asynchronous Port Status
updates to use the new 32-bit version of the Port Information message. If
we get an error, we know we're dealing with older Firmware, and if not,
we'll start getting th new 32-bit Port Capability message formats.

Also, refactor t4_handle_fw_rpl() to handle new 32-bit Port Capability
replies from firmware in t4_handle_get_port_info().

net/cxgbe: improve latency for slow traffic

TX coalescing waits for ETH_COALESCE_PKT_NUM packets to be coalesced
across bursts before transmitting them. For slow traffic, such as
100 PPS, this approach increases latency since packets are received
one at a time and tx coalescing has to wait for ETH_COALESCE_PKT
number of packets to arrive before transmitting.

To fix this:

- Update rx path to use status page instead and only receive packets
when either the ingress interrupt timer threshold (5 us) or
the ingress interrupt packet count threshold (32 packets) fires.
(i.e. whichever happens first).

- If number of packets coalesced is <= number of packets sent
by tx burst function, stop coalescing and transmit these packets
immediately.

Also added compile time option to favor throughput over latency by
default.
