When IMSM_NO_PLATFORM is exported mdadm allows to create array with
partitions or add partition to existing array but there is no
possibilty to assemble it after stopping, see commit 691c6ee1b6bb
("IMSM/DDF: don't recognised these metadata on partitions.").
When searching for hba capabilities first test device and print
corresponding error if it is a partition.
