[PATCH v2 14/25] net/axgbe: remove field of SFP diagnostic support

[Venkat Kumar Ande <venkatkumar.ande@amd.com>]

The driver currently sets an indication of whether the SFP supports, and
that the driver can obtain, diagnostics data.  This isn't currently used
by the driver.  Remove this field and the logic supporting it.
