meta-xilinx: Restructuring meta-xilinx to support multiple layers

As discussed previously on mailing list, we are proceeding with layer
restructuring. For rocko release we will have the following layers

meta-xilinx
        ->meta-xilinx-bsp (current meta-xilinx)
        ->meta-xilinx-contrib

In the subsequent releases we will add other layers from Xilinx
meta-xilinx
        ->meta-xilinx-bsp (current meta-xilinx)
        ->meta-petalinux
        ->meta-xilinx-tools
        ->meta-xilinx-contrib

This will provide one clone to get all the required meta layers from
Xilinx for a complete solution, and the users can blacklist any layer
which they don't want to use using bblayer.conf.
This will enables us to help our vendors/partners to add their reference
designs, board definitions etc.

Recipe changes :
 * Move reference design zybo-linux-bd.bb to meta-xilinx-contrib
 * Move kernel patches realted to zybo-linux-bd-zynq7 board to
   meta-xilinx-contrib
 * Update README

-Build Instructions
-==================
-
-The following instructions require OE-Core meta and BitBake. Poky provides these
-components, however they can be acquired separately.
-
-Initialize a build using the `oe-init-build-env` script. Once initialized
-configure `bblayers.conf` by adding the `meta-xilinx` layer. e.g.:
-
-        BBLAYERS ?= " \
-                <path to layer>/oe-core/meta \
-                <path to layer>/meta-xilinx \
-                "
-
-To build a specific target BSP configure the associated machine in `local.conf`:
-
-        MACHINE ?= "zc702-zynq7"
-
-Build the target file system image using `bitbake`:
-
-        $ bitbake core-image-minimal
-
-Once complete the images for the target machine will be available in the output
-directory `tmp/deploy/images/<machine name>/`.
-
