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.
