[PATCH net-next] net: phy: add extension of phy-mode for XLGMII

[Jie Deng]

The Synopsys DWC_xlgmac core provides a multiplexed 40-Gigabit
Media-Independent Interface (XLGMII, an IEEE 802.3 Clause 81
compliant reconciliation sub-layer) for communication with
the 100/50/40/25-Gigabit PHY and 10-Gigabit Media-Independent
Interface (XGMII, an IEEE 802.3 Clause 46 compliant reconciliation
sub-layer) for communication with the 10-Gigabit PHY.

Currently, There are only interface mode definitions for "xgmii".
This patch adds the definitions for the PHY layer to recognize
"xlgmii" as a valid PHY interface.
