configs/arm_juno: remove defconfig

This defconfig has been failing to build for several months, with
nobody stepping up to fix it. It's time to drop it.

See
https://lore.kernel.org/buildroot/20220806224338.0159e15c@windsurf/
for a notification on August 6, 2022 about the issues with this
defconfig.

-ARM Juno r1/r0
-
-Intro
-=====
-
-These instructions apply to all models of the ARM Juno:
-  - Juno r0 (does not support PCIe)
-  - Juno r1 (supports PCIe)
-  - Juno r2 (Big Cluster with A72)
-
-Buildroot will generate the kernel image, device tree blob, bootloader binaries
-and a minimal root filesystem.
-
-How to build it
-===============
-
-Configure Buildroot
--------------------
-
-Configuring Buildroot is pretty simple, just execute:
-
-  $ make arm_juno_defconfig
-
-Build the rootfs, kernel and DTB
---------------------------------
-
-Note: you will need to have access to the network, since Buildroot will
-download the packages' sources.
-
-You may now build your rootfs with:
-
-  $ make
-
-(This may take a while)
-
-Result of the build
--------------------
-
-After building, you should obtain this tree:
-
-    output/images/
-    +-- rootfs.tar
-    +-- juno.dtb (if Juno r0 is used)
-    +-- juno-r1.dtb (if Juno r1 is used)
-    +-- juno-r2.dtb (if Juno r2 is used)
-    +-- Image
-    +-- bl1.bin
-    +-- bl2.bin
-    +-- bl2u.bin
-    +-- bl31.bin
-    +-- fip.bin
-    +-- scp-fw.bin
-    +-- u-boot.bin
-
-Preparing your rootfs
-======================
-
-Format your pen drive as a ext3 filesystem by executing:
-
-   $ mkfs.ext3 /dev/<your device>
-
-Preparing your rootfs
-======================
-
-Format your pen drive as a ext3 filesystem by executing:
-
-   $ mkfs.ext3 /dev/<your device>
-
-Installing your rootfs
-======================
-
-After mounting the pen drive please execute the following:
-
-   $ sudo tar -xvf output/images/rootfs.tar -C <pen drive mount path>
-
-When completed make sure to unmount the device:
-
-   $ umount <pen drive mount path>
-
-Insert the pen drive in one of the ARM Juno' USB type A connectors.
-
-Configure *.dtb in the boot configuration for Juno r0
-=====================================================

-
-Installing kernel image and DTB
-===============================
-
-1. Connect to the ARM Juno UART0 and execute USB_ON in the terminal
-2. Connect a USB cable between your PC and ARM Juno USB type B connector
-   A mass storage device should appear in your desktop.
-3. Open the software/ folder
-4. Copy the 'Image' file to software/
-5. Copy the 'juno-r1.dtb' (r1), 'juno.dtb' (r0) or juno-r2.dtb (r2) file to software/
-6. Copy the bootloader binaries (bl1.bin and fip.bin) to software/
-7. Press the red button in the front pannel of ARM Juno
-
-At this time, the board will erase the Flash entry for each new item and
-replace it with the lastest ones.
