The DRA72 EVM Rev C straps the DP83867 GigaBit Ethernet phy's RX_DV/RX_CTRL pin in mode 1. Unfortunately, the phy data manual disallows this. Add "ti,dp83867-rxctrl-strap-quirk" property to the phy's device-tree node to allow kernel to enable software workaround for this incorrect strap setting. This is as suggested by the phy's datamanual and ensures proper operation of this PHY. This needs to be done for both instances of this PHY present on the board.
