cpu/or1k: Document no branch delay slot architectures and l.adrp
The 'nd' architectures did not mention what the 'nd' stands for.
Document that these mean 'no brach delay slot'.
cpu/ChangeLog:
yyyy-mm-dd Stafford Horne <shorne@gmail.com>
* or1k.cpu (or64nd, or32nd, or1200nd): Update comment.a
(l-adrp): Improve comment.
