harma,minerva: bmc-storage-module: add Item.Storage

The BMC Storage Module (BSM) is a storage device.  Add the same
interface as the generic `bmc_storage_module.json`.

Tested: Edited JSON manually, restarted entity-manager, observed
`xyz.openbmc_project.Inventory.Item.Storage` is created properly.
