ar71xx: Kernel board definition for PowerCloud CR5000

    Kernel part of support for the PowerCloud Systems CR5000.  The
    CR5000 is a dual-band 802.11n wireless router with 8MB flash,
    64 MB RAM, (unused in stock firmware) USB 2.0 port, and five
    port gigabit ethernet switch.  The CR5000 was sold as hardware for
    the Skydog cloud-managed router service.
