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.

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.
