Move the initialization regcache related fields of the regmap struct to
regcache_init. This allows us to keep regmap and regcache code better

Now that the mfd is using the register map cache there's no need for the

The different devices handled by the WM8994 can be distinguished using
their ID registers so we don't need to rely on the user having registered
the device correctly. Instead do the initial regmap setup with a minimal
configuration only supporting physical I/O and then configure the cache
once we have identified the device.

Merge branch 'topic/cache' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap into HEAD

Describe the register map to the regmap core so that we can use its
diagnostic features and cache support.  This is split out from the patch
using it due to the size so that the actual code change is a bit clearer.

As the various devices are supersets of each other the access maps are
built up by layering the functions on top of each other, though the
interface for specifying the register defaults isn't currently amenable
to this.
