This add pinmux configuration for rgmii interface so that network
driver can be supported on K2G ICE boards. The pinmux configurations
for this are generated using the pinmux tool at
https://dev.ti.com/pinmux/app.html#/default
As this required some BUFFER_CLASS definitions, same is re-used
from the linux defnitions in include/dt-bindings/pinctrl/keystone.h

This patch adds a workaround to reset the phy one time during boot
using GPIO0 pin 10 to make sure, the Phy latches the configuration
from the input pins correctly.

This patch removes the unused phy-mode property from the phy dt node. On
K2G, currently link-interface determines if phy is used or not and is
already set to use rgmii. So this is not needed. Besides phy-mode should
be added to slave interface configuration of the cpsw driver, not in the
phy node.

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.
