    xen/arm: vexpress: Blacklist a list of board specific devices
    
    On Versatile there are a bunch of devices which must not be pass-through to 
any
    guest (power management and cache coherency devices).
    
    This commit also blacklists the HDLCD device because Xen is unable to 
correctly
    map the framebuffer into dom0. Therefore, when Linux will try to access to 
the
    framebuffer, Xen will receive a non-handled data access.
