dt-bindings: ata: ahci-platform: Move dma-coherent to sata-common.yaml



Seeing doubtfully any SATA device working without embedded DMA engine
let's permit the device nodes being equipped with the dma-coherent
property in case if the platform is capable of cache-coherent DMAs.

As a side-effect we can drop the explicit dma-coherent property definition
from the particular device schemas. Currently it concerns the Broadcom
SATA AHCI controller only.
