dt: bindings: net: use boolean dt properties for eee broken modes



The patches regarding eee-broken-modes was merged before all people
involved could find an agreement on the best way to move forward.

While we agreed on having a DT property to mark particular modes as broken,
the value used for eee-broken-modes mapped the phy register in very direct
way. Because of this, the concern is that it could be used to implement
configuration policies instead of describing a broken HW.

In the end, having a boolean property for each mode seems to be preferred
over one bit field value mapping the register (too) directly.

compensate for the board being designed with the lanes swapped.

Mark the corresponding energy efficient ethernet mode as broken and
request the ethernet to stop advertising it.
