Remove fw_cfg hardware interface details from
Documentation/devicetree/bindings/arm/fw-cfg.txt,
and replace them with a pointer to the authoritative
documentation in the QEMU source tree.

Peter Maydell suggested that we describe new devices / DTB nodes in the
kernel Documentation tree that we expose to arm "virt" guests in QEMU.
Although the kernel is not required to access the fw_cfg interface,
"Documentation/devicetree/bindings/arm" is probably the best central spot
to keep the fw_cfg description in.
