[PATCH net] octeontx2-pf: Fix autoneg reporting in ethtool

[nshettyj]

From: Hariprasad Kelam <hkelam@xxxxxxxxxxx>

The driver adds the supported autoneg bit before copying the supported
link modes. The copy clears the bit, so ethtool does not report
supported autoneg correctly.

Add the supported autoneg bit after copying the supported link modes.
Also add the advertised autoneg bit when firmware reports it.

Fixes: 1a50280c25ec ("octeontx2-pf: ethtool physical link status")
