We need to invoke TCPM configuration code, dropping board callbacks means
we need put some #ifdef in dwc3 drivers:

#if CONFIG_IS_ENABLED(TYPEC_TCPM)
static int dwc3_typec_setup(struct udevice *dev, struct dwc3_generic_priv *priv,
                           enum usb_dr_mode mode)
{
        /* Handling tcpm */     
}
#else
static int dwc3_typec_setup(struct udevice *dev, struct dwc3_generic_priv *priv,
                           enum usb_dr_mode mode)
{
        return 0;
}
#endif

I could use above in V3.

Thanks,
Peng
