docs: Remove qemu-upstream HowTo, and link to the wiki page.

Instead of having twice the same HowTo in tree and in the wiki, the one in tree
will become a link to the wiki.

 Using Upstream QEMU with Xen
 ============================
 
-Note
-----
+If you want to build with the QEMU unstable tree, follow the wiki page:
+  [http://wiki.xen.org/wiki/QEMU_Upstream]()
 
-All these steps will become unnecessary after the patches to integrate
-SeaBIOS/QEMU into the Xen build system have been applied.
-
-
-How to build it
----------------
-
-### SeaBIOS
-
-The new device-model needs a different BIOS, SeaBIOS. Clone the repository from:
-
-  - [git://git.qemu.org/seabios.git]()
-  - [http://git.qemu.org/git/seabios.git]()
-
-Put the `.config` file in the appendix at the root of `seabios.git`
-and build SeaBIOS by typing `make`.
-
-In the xen-unstable source tree, add the file `.config` with
-`SEABIOS_DIR = /path/to/seabios.git`.
-To build hvmloader with SeaBIOS, you probably need to `make -C tools/firmware
-clean` first and then `make tools`, to use the new SEABIOS_DIR parameter.
-
-
-### QEMU
-
-Get QEMU upstream source from:
-
-  - [git://xenbits.xensource.com/qemu-upstream-unstable.git]()
-  - [http://xenbits.xensource.com/git-http/qemu-upstream-unstable.git]()
-
-To configure QEMU upstream with support for Xen:
-
-    ./configure --enable-xen --target-list=i386-softmmu --extra-cflags="-I$path_to_xen_source/tools/include -I$path_to_xen_source/tools/libxc -I$path_to_xen_source/tools/xenstore" --extra-ldflags="-L$path_to_xen_source/tools/libxc -L$path_to_xen_source/tools/xenstore"
-
-You can also use other several options such as `--disable-kvm`.
-
-
-How to use QEMU upstream
-------------------------
-
-Only `xl` supports QEMU upstream.
-
-To actually use it, add or change this in your VM configuration file:
+Otherwise, QEMU/SeaBIOS is now integrated into the build system, so you just
+have to specify the device model version in an `xl` config file:
 
     device_model_version = 'qemu-xen'
-    device_model_override = '/path/to/qemu/i386-softmmu/qemu'
-
-NB: In the `qemu-upstream` repository, the default binary name has been
-renamed to `qemu-system-i386`.
