migrate address for completion table and error information table to prevent undefined address access
Completion table and error information table are migrated to a metadata region in DRAM to support predefined project 1.0.0 which does not provide address region for BRAM GreedyFTL-2.7.0.b source for 8-channel 8-way configuration (prebuild 3.0.0) GreedyFTL-2.7.1.b source for 2-channel 8-way configuration (predefied project 1.0.0)
