configs/ci40: remove defconfig

>From the original submitter of this defconfig:

"""
I no longer have access to ci40 board. It would be difficult for me to
maintain it.
"""

And this defconfig currently fails to build with gcc 6.x. Therefore,
drop it.

Fixes:

-*********************
-* MIPS Creator CI40 *
-*********************
-
-This document details how to build and run a Buildroot system on the
-MIPS Creator CI40 platform. For more details about the CI40, see
-https://creatordev.io/ci40-iot-hub.html.
-
-How to build
-------------
-
-$ make ci40_defconfig
-$ make
-
-Prepare USB/MMC for boot
-------------------------
-
-On successful build, "sdcard.img" file will be created in 'output/images'
-folder.
-
-Use following command to write image to bootable device
-
-$ sudo dd if=./output/images/sdcard.img of=/dev/<your-microsd-or-usb-device>
-
-Booting from USB/MMC
---------------------
-
-The boot loader is already present in NOR flash. To boot your newly generated
-Linux and root filesystem, you need to interrupt U-Boot autoboot. Current
-U-Boot is configured with 2 seconds of boot-delay, after expiry of this
-boot-delay timeout U-Boot starts booting the default image. To interrupt
-autoboot, press any key before the boot-delay time expires, U-Boot will
-stop the autoboot process and give a U-Boot prompt. You can now boot to
-your preferred boot method as describe below:
-
-From USB
-  pistachio # run usbboot
-
-From SD-Card
-  pistachio # run mmcboot
-
-Persistent boot command
------------------------
-
-To boot automatically to your preferred boot method, use following command to
-make it persistent, for example to automatically boot to usb:
-
-  pistachio # setenv bootcmd run usbboot
-  pistachio # saveenv
-
-Flash new bootloader
---------------------
-
-The bootloader image will be available in the 'output/images' folder. To flash
-the new bootloader, copy it to the device and use the following command on the
-device:
-
-# flashcp -v u-boot-pistachio_marduk-<version>.img /dev/mtd0
-
-Online docs
------------
-
-Mostly for OpenWRT but it is applicable to Buildroot
