usb: typec: Add partner PD object wrapper
Some port drivers may want to set a Type-C partner as a parent for a
USB Power Delivery object, but the Type-C partner struct isn't exposed
outside of the Type-C class driver. Add a wrapper to
usb_power_delivery_register() which sets the provided Type-C partner
as a parent to the USB PD object. This helps to avoid exposing the
Type-C partner's device struct unnecessarily.
