Remove the reg-io-width property in order to comply with the bindings. The entire bus (PERIC) on which the GS101 serial resides only allows 32-bit register accesses. The reg-io-width dt property is disallowed for the "google,gs101-uart" compatible and instead the iotype is inferred from the compatible.
