imsm: Allow to specify controller for --detail-platform.
Usually, 'mdadm --detail-platform -e imsm' scans all the controllers
looking for IMSM capabilities. This patch provides the possibility
to specify a controller to scan, enabling custom usage by other
processes - especially with the --export switch.
