configs/zynq_zybo: remove defconfig

This defconfig was added in October 2016 and was never updated since
then. It currently fails to build because U-Boot is too old and
doesn't build with host-openssl in version 1.1.x.

On February 13, 2019, the original submitter was notified, but didn't
reply, so let's remove the defconfig for this platform.

-Digilent Zybo
-=============
-
-This is the Buildroot board support for the Digilent Zybo. The Zybo is
-a development board based on the Xilinx Zynq-7000 based All-Programmable
-System-On-Chip.
-
-Zybo information including schematics, reference designs, and manuals are
-available from http://store.digilentinc.com/zybo-zynq-7000-arm-fpga-soc-trainer-board/ .
-
-If you want a custom FPGA bitstream to be loaded by U-Boot, copy it as
-system.bit in board/digilent/zybo/.
-
-Steps to create a working system for Zybo:
-
-1) make zynq_zybo_defconfig
-2) make
-3) write your SD Card with the sdcard.img file using dd by doing
-  $ sudo dd if=output/images/sdcard.img of=/dev/sdX
-4) insert the SD Card and power up your Zybo
-5) Expect serial console on the second USB serial port exposed by the board
-
-The expected output:
-

-Resulting system
-----------------
-Once the build process is finished you will have an image called "sdcard.img"
-in the output/images/ directory.
-
-The first partition is a FAT32 partition created at the beginning of the SD Card
-that contains the following files :
-    /BOOT.BIN
-    /zynq-zybo.dtb
-    /uEnv.txt
-    /system.bit
-    /uImage
-    /u-boot-dtb.img
-
-The second partition is an ext4 partition that contains the root filesystem.
-
-You can alter the booting procedure by modifying the uEnv.txt file
-in first partition of the SD card. It is a plain text file in format
-<key>=<value> one per line:
-
-kernel_image=myimage
-modeboot=myboot
-myboot=...
