arm64: dts: exynos: gs101: remove reg-io-width from serial

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.
