net10 is connected to an SFP module. Unfortunately, the I2C lines are
not connected due to an address conflict. Now that DPAA uses phylink, we
can use in-band-status. This lets us determine whether the link is up or
down instead of assuming it is up all the time. Also fix the phy mode
while we're here.

This should likely go through Shawn Guo's tree, although it could also
go through net-next. It will conflict with [1] which modifies the
adjoining lines and is likely to go through the phy tree.

I'm dropping it from networking pw, FWIW.
