[PATCH v2] dt-bindings: misc: qcom,fastrpc: Compute callbacks can be DMA coherent

[Krzysztof Kozlowski]

Apparently on Qualcomm SM8550 and SM8650 the FastRPC compute callbacks
are DMA coherent:

  sm8650-qrd.dtb: fastrpc: compute-cb@2: 'dma-coherent' does not match any of the regexes: 'pinctrl-[0-9]+'

Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>

Changes in v2:
1. Add missing subject prefix.
