Create an aux device and write an aux driver for the TCPM part.
Sorry, the commit messages may not be described accurately enough. This patch adds mux/switch operations to the PHY driver to improve communication with the TCPM framework. Since this PHY is a combo USB/DP PHY, it requires configuration changes to the PHY lanes based on the USB-C plug orientation (CC logic), similar to the existing extcon mechanism implementation. Of course, the original extcon functionality will remain fully compatible.
