usb: usb251xb: Use of_device_get_match_data()

Use the more modern API here instead of using of_match_device() and
avoid casting away const from the returned pointer by pushing the const
type through to the users. This nicely avoids referencing the match
table when it is undefined with configurations where CONFIG_OF=n and
avoids const issues.
