    rockchip: gru: pass poweroff gpio parameter to BL31
    
    To support gpio power off SOC, we need to pass the power off
    gpio parameter to BL31. Gru reuse tsadc overtemp pin as power
    off gpio, so need to iomux to gpio function when use gpio power
    off function, either in bl31 or depthcharge.
