  regmap: allow upshifting register addresses before performing operations (2023-04-07 17:28:19 +0100)

regmap: Updates for v6.4

This is a much bigger change for regmap than is normal, the main things
being the addition of some KUnit coverage and a maple tree based
register cache which longer term is likely to replace the rbtree cache
except possibly for very small register maps.  While it's complete
overkill for most applications the code for maple trees is there and
there are some larger, sparser devices where the data structure is a
better fit.

The maple tree support is still a work in progress but already useful,
there's some conversions of drivers ready to go after the merge window.

 - Support for shifting register addresses up as well as down, there's a
   use cases with memory mapped MDIO.
 - Refactoring of the type configuration in regmap-irq to allow access
   to driver data in the handler, needed by some GPIO devices.
 - Some initial KUnit coverage, the bulk of the driver facing API is
   covered but there's holes and things like the data marshalling for
   bytestream buses are just not covered in the slightest.
 - Removal of the compressed cache type, it had zero users and was
   getting in the way of KUnit.
 - Addition of a maple tree based register cache, there's more work to
   do but it's already useful for some devices with a flatter data
   structure than rbtree and getting to use all the optimisation work
   Liam is doing.
