Subject: [PATCH v3 0/5] regcache: Split out ->populate() and use it

This is a refactoring series to decouple cache initialisation and population.
On its own it has no functional impact but will be used in the further
development. Besides that I found this split useful on its own (from the design
perspective). That's why I decided to send it out as is separately from a bigger
(and ongoing) work.

Changelog v3:
- added missing space (Mark)
- collected tags (Sander)

Changelog v2:
v2: https://lore.kernel.org/r/20251030173915.3886882-1-andriy.shevchenko@linux.intel.com
- rebased on top of the recent regcache changes (Mark)
- a new clean up patch induced by the previous

v1: https://lore.kernel.org/r/20251029073131.3004660-1-andriy.shevchenko@linux.intel.com
