uio: dfl: add HSSI subsystem feature id 

Add the Device Feature List (DFL) feature id for the
High Speed Serial Interface (HSSI) Subsystem to the
table of ids supported by the uio_dfl driver.

The HSSI Subsystem is a configurable set of IP blocks
to be used as part of a Ethernet or PCS/FEC/PMA pipeline.
Like the Ethernet group used by the N3000 card, the HSSI
Subsystem does not fully implement a network device from
a Linux netdev perspective and is controlled and monitored
from user space software via the uio interface.

The Feature ID table of DFL can be found:
