usb: typec: altmodes: add typec_cable_ops to typec_altmode
Add typec_cable_ops struct for enter, exit, and vdm. The struct is added
to typec_altmode so port alt modes can have access to partner and cable
specific callbacks, and alt mode drivers can specify operations over SOP'
and SOP'' without modifying the existing API.
typec_port_register_cable_ops is added as a new symbol for port drivers
to use to register cable operations to their registered port alt modes.
