regmap: Updates for v6.19

Another small update for regmap, we have one new feature plus a little
bit of cleanup:

 - Support for sparseness information in the flat cache, allowing users
   that really need the performance properties it provides to benefit
   from the interface and startup time improvements that sparsness provides
   without needing to go all the way to a more fancy data structure.
 - Cleanup work from Andy Shevchenko, refactoring the cache interface
   in preparation for some future stuff he's working on.

----------------------------------------------------------------
Andy Shevchenko (6):
      regcache: Add ->populate() callback to separate from ->init()
      regcache: rbtree: Split ->populate() from ->init()
      regcache: flat: Remove unneeded check and error message for -ENOMEM
      regcache: flat: Split ->populate() from ->init()
      regcache: maple: Split ->populate() from ->init()
      regmap: i3c: Use ARRAY_SIZE()
