[net,0/4] net: bcmgenet: restore internal EPHY support

I managed to get my hands on an old BCM97435SVMB board to do some
testing with the latest kernel and uncovered a number of things
that managed to get broken over the years (some by me ;).

This commit set attempts to correct the errors I observed in my
testing.

The first commit applies to all internal PHYs to restore proper
reporting of link status when a link comes up.

The second commit restores the soft reset to the initialization of
the older internal EPHYs used by 40nm Set-Top Box devices.

The third corrects a bug I introduced when removing excessive soft
resets by altering the initialization sequence in a way that keeps
the GENETv3 MAC interface happy.

Finally, I observed a number of issues when manually configuring
the network interface of the older EPHYs that appear to be resolved
by the fourth commit.

Thank you very much for addressing all of those problems!

Series applied and queued up for -stable.

Thanks.
