configs/pandaboard_defconfig: drop defconfig

The defconfig has failed to build since May with the change to GCC 13.x,
E.G.:

https://gitlab.com/buildroot.org/buildroot/-/jobs/6865597768

I no longer have access to a pandaboard.  Pandaboard/omap4 support has
recently been dropped from u-boot:
https://lists.denx.de/pipermail/u-boot/2024-July/558846.html

And (part of) the kernel support is also getting removed:
https://patchwork.kernel.org/project/linux-media/patch/815a789d-85a5-44a1-8b9c-429ac0101e3f@xs4all.nl/

So drop the defconfig here as well.

-Pandaboard
-==========
-
-This file documents the Buildroot support for the Pandaboard, a
-low-power, low-cost single-board computer development platform based
-on the Texas Instruments OMAP4 system on a chip (SoC).
-
-Configuring and building Buildroot
-----------------------------------
-
-Start from the defconfig:
-
-  $ make pandaboard_defconfig
-
-You can edit build options the usual way:
-
-  $ make menuconfig
-
-When you are happy with the setup, run:
-
-  $ make
-
-The result of the build with the default settings should be these files:
-
-  output/images
-  +-- MLO
-  +-- omap4-panda-a4.dtb
-  +-- omap4-panda.dtb
-  +-- omap4-panda-es.dtb
-  +-- rootfs.ext4
-  +-- sdcard.img
-  +-- u-boot.img
-  +-- zImage
-
-How to write the SD card
-------------------------
-
-Once the build process is finished you will have an image called "sdcard.img"
-in the output/images/ directory.
-
-Copy the bootable "sdcard.img" onto an SD card with "dd":
-
-  $ sudo dd if=output/images/sdcard.img of=/dev/sdX
-
-Where /dev/sdX is the device node of your SD card (may be /dev/mmcblkX
-instead depending on setup).
