[PATCH net-next v4 2/5] ionic: Update ionic_if.h with new extra port stats

[Eric Joyner <eric.joyner@amd.com>]

Add a new structure to report additional statistics from the firmware to
struct ionic_port_info. This new struct currently only contains FEC
related statistics, but any new port-level statistics collected by the
firmware would go into it.

The new structure is located in the same area as the unused
ionic_port_pb_stats structure, so this patch also removes that since it
was never used in this driver.

Finally, to indicate firmware support for the new structure, introduce a
new device capability that the driver can use to see if the attached
device supports reporting these extra stats.
