Core: Add ZI and RW regions for seucre data in memory check

The ER_TFM_DATA zero data region is not included in the section between
Image$$ER_TFM_DATA$$Base and Image$$ER_TFM_DATA$$Limit. If the client
data buffer comes from the ZI region, the memory check function will
fail. So use RW and ZI region respectively to do a memory check to fix
this issue.
