[PATCH 05/14] usb: typec: tps6598x: Start using struct typec_operations

[Heikki Krogerus <heikki.krogerus@xxxxxxxxxxxxxxx>]

Supplying the operation callbacks as part of a struct
typec_operations instead of as part of struct
typec_capability during port registration. After this there
is not need to keep the capabilities stored anywhere in the
driver.
