All the m0 code run in SRAM before, but we need to watch PMU_POWER_ST
when SOC enter into FSM, and SRAM will shutdown during this time, so
this code need run in PMUSRAM. But PMUSRAM only 8K space, we can not
put all the m0 binary into PMUSRAM, Split the M0 binary into two, dram
part still run in SRAM, and suspend part run in PMUSRAM.

This CL supports add M0 source code to built into the bl31.bin, the
goal is that we can load the M0 code binary into SRAM and execute it.

We need the M0 help us to clean the power_mode_en bit during the AP
PMU enter the state machine with interrupt, and avoid to the AP can
not exit the loop forever.
