This patch adds dt node for DP83867 phy used on K2G ICE board and
also enable netcp device nodes for the board.

EVM hardware spec recommends to add 0.25 nsec delay in the tx
direction and 2.25 nsec delay in the rx direction for internal
delay in the clock path to be on the safer side.

The board straps RX_DV/RX_CTRL pin of on board DP83867 phy in mode
1. Unfortunately, the phy data manual disallows this. Add
ti,dp83867-rxctrl-strap-quirk in the phy node to allow software to
enable workaround suggested for this incorrect strap setting. This
ensures proper operation of this PHY.

The dts bindings are kept in sync with that from 4.14.y linux
kernel. This required the pinmux device related bindings to be
commented out to allow for compilation.
