platform: goldfish: pipe: add devicetree bindings 



Add bindings so we don't need to rely on goldfish virtual bus for
probing any more, which means we don't need ARM and MIPS goldfish
board code for instantiating the bus.

In the long term we would like to move towards replacing the Android
pipe with virtio-vsock that is currently under development.

Android Goldfish QEMU Pipe



Andorid pipe virtual device generated by android emulator.



Required properties:



- compatible : should contain "google,android-pipe" to match emulator

- reg        : <registers mapping>

- interrupts : <interrupt mapping>



Example:



	android_pipe@a010000 {

		compatible = "google,android-pipe";

		reg = <ff018000 0x2000>;

		interrupts = <0x12>;

	};
