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
