[PATCH v3 03/12] dt-bindings: serial: samsung: do not allow reg-io-width for gs101

[Tudor Ambarus]

All gs101 serial ports are restricted to 32-bit register accesses.
This requirement will be inferred from the compatible. Do not allow
the reg-io-width property for the google,gs101-uart compatible.
