    ARM: dts: at91: sam9g20ek: enable udc vbus gpio pinctrl
    
    [ Upstream commit 40a2226e8bfacb79dd154dea68febeead9d847e9 ]
    
    We set the PIOC to GPIO mode. This way the pin becomes an
    input signal will be usable by the controller. Without
    this change the udc on the 9g20ek does not work.
