mfd: fusb302: add gpio control vbus discharge

When type-c vbus output power down or disconnect charging input, the
type-c vbus voltage discharge to 0V take a long time, during this time
residual voltage would affect charge circuit in some platforms（e.g.
rk3399-tve1205g board）. So we need add fast discharge circuit, then use
a gpio control it.
