> During initial checks the ANX7625 bridge can be powered on before setting up
> the Type-C port. At this point, when
> anx7625_ocm_loading_check() checks if it can disable PD or not, it will notice
> that typec_port is not set and disable PD, breaking orientation and HPD
> handling. Unify the check between anx7625_ocm_loading_check()
> anx7625_i2c_probe() and anx7625_typec_register() and check for the
> presence of the "connector" node.
