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
