The default partition table type for arm64/* and armhf/efi platforms is

The default partition table type is used by both manual creation of a
new partition table in normal install and guided partitioning using an
entire disk.

Proposed solutions:
- Force MSDOS default type on SD/eMMC if the platform boot location
overlaps with the GPT area.
- Force MSDOS default type on SD/eMMC if the platform boot location
overlaps with the GPT area and a boot loader is detected.
- Force MSDOS default type on SD/eMMC if the platform boot location
overlaps with the GPT area and a boot loader is detected or the platform
does not support an alternate boot location.
- Additionally for automatic partitioning, if the current partition
table is GPT, then just remove all partitions instead of creating a new
partition table, assuming that the existing partition table does not
overlap with U-Boot.
