usb: typec: ucsi: Fix cable registration
The Cable PD Revision field in GET_CABLE_PROPERTY was
introduced in UCSI v2.1, so adding check for that.
The cable properties are also not used anywhere after the
cable is registered, so removing the cable_prop member
from struct ucsi_connector while at it.
Fixes: 38ca416597b0 ("usb: typec: ucsi: Register cables based on GET_CABLE_PROPERTY")
