[Buildroot] [PATCH v5 07/10] configs/socionext_developerbox_defconfig: new config for Developerbox

[Dick Olsson]

This introduces configuration for the Socionext Developerbox, an
Aarch64 workstation built with ARM Trusted Firmware and EDK2 firmware.

Signed-off-by: Dick Olsson <hi at senzilla.io>

---

Revision 5:

 * Replaced kernel EFI stub mode with GRUB2 for more convenience
 * The GRUB2 package handles the efi-part image
 * Simplified the post script
 * Removed the startup.nsh in favour of that provided by GRUB2
 * Re-exported the defconfig

Revision 4:

 * Renamed post-image.sh to assemble-flash-images
 * Updated to Linux LTS kernel 5.10
 * Added startup.nsh script for auto-booting from the EFI shell
