rockchip: add M0 source code and build system for RK3399 

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.
