Due to datasheet of rt3883 SoC rgmii1 port handles pins 84-95 and rgmii2 port
handles pins 72-83. When this function ports gets added to rt3883_pinmux_data
there's wrong pinmux bits set (RT3883_GPIO_MODE_GE1 manages 84-95 pins and
RT3883_GPIO_MODE_GE2 manages 72-83). So when enabling rgmii2 as GPIO driver
confuses hardware and nothing work, neither rgmii nor gpio.
Also in '0030-pinctrl-ralink-add-pinctrl-driver.patch' typo in name of rgmii2
port.
