partition_manager: Make tfm storage partions avoid partitioning conflict

With the previous method, both tfm_storage partitions (its, ps, etc)
were placed "before: mcuboot_primary". This could lead to a case
where mcuboot was placed after the tfm_storage partitions.
To avoid this, instead place "after" mcuboot or tfm_secure.
