[PATCH 3/6] libmm-libbsp-shared. Files shared between all target BSPs and low-level implementations for libmm. These shared files contain mm.h which is a link between high-level score api and low-level implemenation of libmm. mm.h contains function declarations which should be implemented by target BSP to support libmm. no_memorymanagement.c contains stubs for BSPs that do not support libmm.

mm_config_table.c
can include it and recognize such a type.
 I can't include arm-cp15-start.h (which it has an exact definition)
to mm_config_table.c because there will be a multiple-definition
compilation error (as arm-cp15-start.h implements some routines) because
mm.c also includes it.
