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

+ZynqMP - PMU ROM
+----------------
+
+Since Xilinx tool release v2017.1 multiple components (arm-trusted-firmware,
+linux, u-boot, etc.) require the PMU firmware to be loaded. For QEMU this also
+means that the PMU ROM must be loaded so that the PMU firmware can be used.
+
+The PMU ROM is not available for download separately from a location that can be
+accessed without a Xilinx account. As such the PMU ROM must be obtained manually
+by the user. The PMU ROM is available in the ZCU102 PetaLinux BSP, but can be
+extracted without the need for the PetaLinux tools.
+
+Download the BSP (you will need a Xilinx account and agreement to terms):
+
+https://www.xilinx.com/member/forms/download/xef.html?filename=xilinx-zcu102-v2017.1-final.bsp&akdm=1
+
+Once downloaded the PMU ROM can be extracted using the following command and
+place `pmu-rom.elf` in the `deploy/images/zcu102-zynqmp/` directory.
+
+```
+# tar -O -xf xilinx-zcu102-v2017.1-final.bsp \
+    xilinx-zcu102-2017.1/pre-built/linux/images/pmu_rom_qemu_sha3.elf > pmu-rom.elf
+```
