We have managed versions of the other regmap allocation functions, it
makes sense for consistency to have managed versions of these too.  I
think there's a meaningful difference between a simple and expected
wrapper like these and infrastructure which hasn't been proved out by
users.

Please delete unneeded context from mails when replying.  Doing this
makes it much easier to find your reply in the message, helping ensure
it won't be missed by people scrolling through the irrelevant quoted
material.
