[PATCH 8/9] Add support for the BeaglePlay board

[Jan Kiszka <jan.kiszka@siemens.com>]

From: Jan Kiszka <jan.kiszka@siemens.com>

This creates a minimal image for the BeaglePlay board [1], using UEFI as
boot method.

That is requiring some extra work so that the image can also be used on
SD cards: The ROM loader only supports legacy DOS partition tables, but
UEFI needs GPT. We address this by creating a hybrid image with both
partition tables in place, first allowing wic to generate a GPT table,
then using fdisk to add a DOS partition entry at least for the UEFI boot
partition.
