dt-bindings: arm: Convert QEMU fw-cfg to DT schema

Browse source

Convert the QEMU fw-cfg binding to DT schema format. As this binding is
also used on Risc-V now, drop any architecture references and move to a
common location. The fw-cfg interface has also gained some DMA support
which is coherent, so add the missing 'dma-coherent'.
