[PATCH v2] dt-bindings: soc: ti: pruss: Add dma-coherent property

Update the PRUSS schema file to include the dma-coherent property
that indicates the coherency of the IP. The PRUSS IPs on 66AK2G
SoCs do use this property.
The new added dma-coherent property is a required property _only_
for 66AK2G SoCs and is not required/applicable for other SoCs, so
the binding is backward compatible for other SoCs. This update is
being done before the corresponding dts nodes can be added for 66AK2G
SoCs.
