    ramips: fix PWM pin mux conflict in dtsi
    
    GPIO18 and GPIO19 on OMEGA2(+) should be GPIO mode, enable PWM lead to a conflict
    
    [    0.290633] rt2880-pinmux pinctrl: pin io18 already requested by pinctrl; cannot claim for 10005000.pwm
    [    0.299722] rt2880-pinmux pinctrl: pin-18 (10005000.pwm) status -22
    [    0.305729] rt2880-pinmux pinctrl: could not request pin 18 (io18) from group pwm0  on device rt2880-pinmux
    [    0.315131] mtk-pwm 10005000.pwm: Error applying setting, reverse things back
    
    Keep PWM disabled.
