The change looks good, but whilst it won't cause any problems, it
seems a bit weird not to convert wm8997, wm8998 and cs47l24.
These are part of the same driver as wm5102 and wm5110.

Nevermind, it seems those parts were already converted.

If all of this is true, is there any reason to keep REGCACHE_RBTREE
around?  If not, perhaps REGCACHE_RBTREE should be treated as
REGCACHE_MAPLE in the regmap core code first, followed by a single
tree-wide patch to replace REGCACHE_RBTREE?

There is a very small niche for devices where cache syncs are a
particularly important part of the workload where rbtree's choices might
give better performance, especially on systems with low end CPUs.

The REGCACHE_* value is specified by the device, not by the CPU?
While some of these MFD devices are on-SoC, and thus there is some
relation between device and CPU, several others (e.g. PMICs) are
external, and thus might be present on systems with a variety of CPU
performance.

Perhaps the value should depend on some CPU heuristic instead?
