[rfc/patch] use hvc for xen console

[kraxel at suse.de (Gerd Hoffmann)]

  Hi,

Here is a patch (on top of the paravirt patch queue) which makes xen
guests use the hvc_console.c infrastructure for the console, thereby
greatly reducing the amount console code.  xvc0 is gone too, hvc0 is
used instead.

cheers,
  Gerd
