Users would like to be able to create a FIT with hashed images using using a given algorithm in auto mode. Allow them to use the existing -o option for this.

In commit b93a65209c4a ("mkimage: fit: Support signed configurations in 'auto' FITs"), the examples lead me to believe this was already the behavior, however -o only affects auto-conf mode.

The change in this commit does not affect the auto-conf behaviour.

Signed-off-by: Joel Stanley joel@jms.id.au --- RFC. This is useful in testing that the hash infrastructure is working. If there's no appetite for changing the mkimage behaviour then I understand.
