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

+From 2112c9ded01ddd08f0e31e5ce23eecac6c04e8c4 Mon Sep 17 00:00:00 2001
+From: David Holsgrove <david.holsgrove@petalogix.com>
+Date: Mon, 6 Feb 2012 10:28:29 +1000
+Subject: [PATCH 06/16] [Patch, microblaze]: Add initial port of linux
+ gdbserver
+
+add gdb_proc_service_h to gdbserver microblaze-linux
+
+gdbserver needs to initialise the microblaze registers
+
+other archs use this step to run a *_arch_setup() to carry out all
+architecture specific setup - may need to add in future
+
+ * add linux-ptrace.o to gdbserver configure
+ * gdb/configure.tgt: Set build_gdbserver=yes
+ * Update breakpoint opcode
+ * fix segfault on connecting gdbserver
+ * add microblaze_linux_memory_remove_breakpoint
+ * add set_solib_svr4_fetch_link_map_offsets
+ * add set_gdbarch_fetch_tls_load_module_address
+ * Force reading of r0 as 0, prevent stores
