SQA images should allow support rollback to 0.0.22

Rolling back to 0.0.22 requires erasing the INFO1 rollback protection
space, as current RW level is at two, and 0.0.22 is at one.

The only way to erase INFO1 is to run a node locked prod signed 0.3.22
image. But 0.3.22 will destroy board ID along with the rollback spaces
AND it is not capable of rollback, so to roll back to a lower than
0.3.22 version one still needs to run the SQA image. 0.3.22 will not
allow to restore the Board ID either.

Another problem is that SQA image would update the rollback INFO1
space, thus again preventing 0.0.22 from running.

This patch alleviates the situation by allowing the SQA images to
write Board ID fields and preventing SQA images from updating rollback
space in INFO1.
