Since the DMA-engine of the RK3399 cannot directly copy the ATF SRAM/PMUSRAM memory sections to their destination, we need to use bounce-buffers. This results in allocation of a huge amount of heap memory, which can't be reused (because of simple-malloc).
Therefore we enable the static bounce buffer method.
