regmap: Changes for v7.4

This is a relatively busy release, mostly due to the general cleanup
work which people have been doing throughout the kernel - for regmap
that's mostly been some work from Peng Fan.  I also added some more
tests for the sparse caches to catch some gotchas people might run into
trying to improve the maple cache.

 - Test very high register numbers to help people avoid a nasty gotcha
   trying to optimise the maple cache.
 - Make more use of scoped lock and allocation guards.
 - A couple of other smaller improvements and fixes.
