usb: typec: Factor out non-PD fwnode properties

Basic programmable non-PD Type-C port controllers do not need the full
TCPM library, but they share the same devicetree binding and the same
typec_capability structure. Factor out a helper for parsing those
properties which map to fields in struct typec_capability, so the code
can be shared between TCPM and basic non-TCPM drivers.
