When BL31 software is sending data through a communication channel,
there's a chance that the final portion of the data could become
disrupted, if another software (BL32/RMM) starts setting up the
channel at the same time. To solve this issue, make sure to flush the
console data from BL31, before initializing BL32/RMM. This makes sure
that the communication stays reliable.
