dt-bindings: net: qrtr: Add FIFO transport bindings 

The QRTR FIFO driver acts as a transport driver between virtual
machines for the QRTR core logic. Document the bindings for the shared
memory region and interrupt resources.

Qualcomm Technologies, Inc. IPC Router FIFO Transport



Required properties:

- compatible:	should be "qcom,ipcr-fifo-xprt"

- reg:		the irq register to raise an interrupt

- interrupts:	the receiving interrupt line

- qcom,ipc-shm:	reference to shared memory phandle



Example:



	fifo_vipc_irq@176 {

		compatible = "qcom,ipcr-fifo-xprt";

		reg = <0x176>;

		interrupts = <0x0 0x142 0x1>;

		qcom,ipc-shm = <&ipc-shm>;

	};



	ipc-shm: shared-buffer@85af7000 {

		compatible = "qcom,hypervisor-shared-memory";

		phandle = <0x1e4>;

		reg = <0x0 0x85af7000 0x0 0x9000>;

		label = "ipc_shm";

		qcom,tx-is-first;

	};
