    mediatek: drop pwm7_pins from Buffalo WSR-2533DHP2
    
    MediaTek MT7622 doesn't support ch7 of PWM and pinctrl groups were dropped from
    driver source[0]. So pwm7-related groups are unavailable now, then, kernel shows a
    warning.
    
    [    0.370264] mt7622-pinctrl 10211000.pinctrl: invalid group "pwm_ch7_2" for function "pwm"
    
    Drop that pinmux from pinctrl node.
