Hello

The DP83TD510 is an Ethernet PHY supporting single pair of twisted wires. The
PHY is capable of 10Mbps communication over long distances and exceeds the
IEEE 802.3cg 10BASE-T1L single-pair Ethernet specification.  The PHY supports
various voltage level signalling and can be forced to support a specific
voltage or allowed to perfrom auto negotiation on the voltage level. The
default for the PHY is auto negotiation but if the PHY is forced to a specific
voltage then the LP must also support the same voltage.

Add the 10BASE-T1L linkmodes for ethtool to properly advertise the PHY's
capability.
