phy: ti: j721e-wiz: Manage TypeC lane swap if typec-dir-gpios not specified

It's possible that the Type-C plug orientation on the DIR line will be
implemented through hardware design. In that situation, there won't be
an external GPIO line available, but the driver still needs to address
this since the DT won't use the typec-dir-gpios property.

Add code to handle LN10 Type-C swap if typec-dir-gpios property is not
specified in DT.
