Subject: [PATCH net v2 3/3] net: phy: micrel: Remove DT option lan8814,ignore-ts

When the PHY and the MAC are capable of doing timestamping, the PHY has
priority. Therefore the DT option lan8814,ignore-ts was added such that
the PHY will not expose a PHC so then the timestamping was done in the
MAC. This is not the correct approach of doing it, therefore remove
this.
