board/bsc9131rdb: Add DSP side tlb and laws

Browse Source 
BSC9131RDB is a Freescale Reference Design Board for
BSC9131 SoC which is a integrated device that contains
one powerpc e500v2 core and one DSP starcore.

To support DSP starcore
-Creating LAW and TLB for DSP-CCSR space.
-Creating LAW for DSP-core subsystem M2 memory

@ -422,6 +422,13 @@ The following options need to be configured:
This is the value to write into CCSR offset 0x18600
according to the A004510 workaround.
CONFIG_SYS_FSL_DSP_M2_RAM_ADDR
This value denotes start offset of M2 memory
which is directly connected to the DSP core.
CONFIG_SYS_FSL_DSP_CCSRBAR_DEFAULT
This value denotes start offset of DSP CCSR space.
- Generic CPU options:
CONFIG_SYS_BIG_ENDIAN, CONFIG_SYS_LITTLE_ENDIAN
