Use BLS fragment filename as menu entry id and for sort criterion
The BLS config filenames are guaranteed to be unique, so they can be
used as GRUB2 entry id and can also be used to sort the menu entries.

Subject: [PATCH 168/250] arm64: make sure fdt has #address-cells and
#size-cells properties
Recent upstream changes to kexec-tools relies on #address-cells
and #size-cells properties in the FDT. If grub2 needs to create
a chosen node, it is likely because firmware did not provide one.
In that case, set #address-cells and #size-cells properties to
make sure they exist.
