Introduce a device align attribute.  While doing so, rename the region
align attribute to be more explicitly named as so, but keep it named as
@align to retain the API for tools like daxctl.

Changes on align may not always be valid, when say certain mappings were
created with 2M and then we switch to 1G.  So, we validate all ranges
against the new value being attempted, post resizing.

The signoff chain implies that this was From:Joao.  Please clarify?

Yes, sorry, my script to squash the fix rewrote the author and I
failed to catch it. This indeed should be:

From: Joao Martins <redacted>

I double-checked, and it looks like this was the only one in the
series with that problem.
