Subject: [PATCH v2 2/4] usb: typec: hd3ss3220: use typec_get_fw_cap() to
 fill typec_cap

The type, data, and prefer_role properties were previously hard-coded
when creating the struct typec_capability.

Use typec_get_fw_cap() to populate these fields based on the
respective fwnode properties, if present.
