usb: phy: tahvo: Use devm_extcon_dev_[allocate|register]() and replace deprecated API 

This patch uses the devm_extcon_dev_[allocate|register]() to manage the
resource automatically and replace deprecated API as following:
- extcon_[set|get]_cable_state(*edev, char *) -> extcon_[set|get]_cable_state_(*edev, id)
