[PATCH v2 3/4] spi: dt-bindings: samsung: allow controller-data to be optional

[Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxxxxx>]

The Samsung SoC SPI bindings requires to provide controller-data node
for each of SPI peripheral device nodes.  Make this controller-data node
optional, so DTS could be simpler.
