Merge branch 'net-phy-T1-support'

Andrew Lunn says:

====================
net: phy: T1 support

T1 PHYs make use of a single twisted pair, rather than the traditional
2 pair for 100BaseT or 4 pair for 1000BaseT. This patchset adds link
modes for 100BaseT1 and 1000BaseT1, and them makes use of 100BaseT1 in
the list of PHY features used by current T1 drivers.
====================
