disk: part_dos: print partition UUID in partition list
This information may be useful to compare against command "part uuid", or if you want to manually paste the information into the kernel command-line. Signed-off-by: Stephen Warren <swarren@nvidia.com> [trini: print_one_part / print_part_dos output strings didn't quite match before the changes] Signed-off-by: Tom Rini <trini@ti.com>
