Subject: net: phy: initialise phydev speed and duplex sanely
Patch-mainline: v5.5-rc1
Git-commit: a5d66f810061e2dd70fb7a108dcd14e535bc639f
References: bsc#1154353

When a phydev is created, the speed and duplex are set to zero and
-1 respectively, rather than using the predefined SPEED_UNKNOWN and
DUPLEX_UNKNOWN constants.

There is a window at initialisation time where we may report link
down using the 0/-1 values.  Tidy this up and use the predefined
constants, so debug doesn't complain with:

"Unsupported (update phy-core.c)/Unsupported (update phy-core.c)"

when the speed and duplex settings are printed.
