This clearly brings up the question about the code style line length, which in

xen/efi: Restrict check for DT boot modules on EFI boot
arm/efi: Use dom0less configuration when using EFI boot

When Xen is started as EFI application, it is checking
the presence of multiboot,module in the DT, if any is
found, the configuration file is skipped.
Restrict this check to just any multiboot,module that
is a direct child of the /chosen node.

The property holds a string containing the file name of the
binary that shall be loaded by the uefi loader from the filesystem.
