zynq_zc706: bump U-Boot to xilinx-v2016.2

This is the latest release tag in the Xilinx repository, based on
U-Boot v2016.01 in the mainline.  It includes proper ps7_init_gpl.c/h
in it, so builds working SPL without any manual intervention.

BR2_TARGET_UBOOT_BOARD_NAME should be changed to zynq_zc706 since
U-Boot now has separate defconfig files for ZC702 and ZC706 boards.

BR2_TARGET_UBOOT_SPL_NAME should be changed to spl/boot.bin since
the Zynq image support for the mkimage tool was upstreamed and it
now generates boot.bin under spl/ directory.

-uboot.bin  -- U-Boot SPL w/ Xilinx boot.bin wrapper
----------------------------------------------------
-
-Due to licensing issues, the files ps7_init.c/h are not distributed
-with the U-Boot source code.  These files are required to make a
-boot.bin file.
-
-If you already have the Xilinx tools installed, the following sequence
-will unpack, patch and build the rfs, kernel, uboot, and uboot-spl.
-
-make zynq_zc706_defconfig
-make uboot-patch
-cp ${XILINX_SDK_LIB}/hwplatform_templates/ZC706_hw_platform/ps7_init.{c,h} \
-   output/build/uboot-xilinx-v2014.1/board/xilinx/zynq/
-
-Where ${XILINX_SDK_LIB} is ${XILINX}/SDK/${VERSION}/data/embeddedsw/lib.
-
-After copying these files into the U-Boot source tree, you can
-continue the build with:
-
-make
-
-*Notice*
-While the build will successfully complete without the ps7_init.*
-files, the uboot.bin file generated by this configuration will not
-function properly on the ZC706. Therefore, it is imperative that the
-ps7_init.* files be copied into the U-Boot source tree any time the
-clean, or uboot-dirclean targets are executed.
-
-Resulting system
-----------------
-
-A FAT32 partition should be created at the beggining of the SD Card
-and the following files should be installed:
-
-- boot.bin
-- devicetree.dtb
-- uImage
-- uramdisk.image.gz
-- u-boot.img
-
-All needed files can be taken from <output>/images/
-
-cp <output>/images/boot.bin /media/sdcard/
-cp <output>/images/uImage /media/sdcard/
-cp <output>/images/u-boot.img /media/sdcard/
-cp <output>/images/zynq-zc706.dtb /media/sdcard/devicetree.dtb
-cp <output>/images/rootfs.cpio.uboot /media/sdcard/uramdisk.image.gz
+Steps to create a working system for ZC706 board:
+
+1) make zynq_zc706_defconfig
+2) make
+3) All needed files will be available in the output/images directory.
+   Create a FAT32 partition at the beginning of your SD Card and copy files:
+     - boot.bin
+     - u-boot.img
+     - uImage
+     - uramdisk.image.gz (should be renamed from rootfs.cpio.uboot)
+     - devicetree.dtb (should be renamed from zynq-zc706.dtb)
+   into your SD card
+4) boot your ZC706 board
+
+You can alter the booting procedure by creating a file uEnv.txt
+in the root of the SD card. It is a plain text file in format
+<key>=<value> one per line:
+
+kernel_image=myimage
+modeboot=myboot
+myboot=...
