The Broadcom iProc SDHCI controller supports DMA, but its binding
schema does not allow the 'dma-coherent' property.
As a result, dtbs_check reports the following validation errors
on the Northstar2 SoC:
mmc@66420000 (brcm,sdhci-iproc-cygnus): Unevaluated properties
are not allowed ('dma-coherent' was unexpected)
mmc@66430000 (brcm,sdhci-iproc-cygnus): Unevaluated properties
are not allowed ('dma-coherent' was unexpected)
Allow the 'dma-coherent' property in the schema to fix the validation
errors and accurately reflect the hardware capability.
