Add pinmux configurations for RGMII based CPSW ethernet to am335x-evm. In this patch, only single named mode/state is added and these pins are configured during pinctrl driver initialization. Default mode is nothing but the values required for the module during active state. With this configurations module is functional as expected. Todo: - if an idle state is available for pins, add support for it.
