s390/ism: Introduce struct ism_dmb
Conceptually, a DMB is a structure that belongs to ISM devices. However, SMC currently 'owns' this structure. So future exploiters of ISM devices would be forced to include SMC headers to work - which is just weird. Therefore, we switch ISM to struct ism_dmb, introduce a new public header with the definition (will be populated with further API calls later on), and, add a thin wrapper to please SMC. Since structs smcd_dmb and ism_dmb are identical, we can simply convert between the two for now.
