[PATCH] dt-bindings: soc: samsung: usi: refer to dtschema for children

[Krzysztof Kozlowski]

Explicitly reference the dtschema for USI children implementing specific
serial protocol (I2C, SPI, UART).  The SPI schema is not yet accepted,
so it will be provided later.

This whole paragraph doesn't make much sense now, because the doc
links it refers to are removed in this patch. Maybe it's better to
just remove the whole paragraph?
