[PATCH] mfd: Improve performance of later WM1811 revisions

[PATCH] mfd: Improve performance of later WM1811 revisions

[Mark Brown]

Apply tunings from earlier silicon revisions to revisions up to D and also
tweak an additional setting for improved DC servo performance.

As this applies on top of things queued in regmap (the patches stuff)
and seems fairly obvious from a framework point of view I've just gone
ahead and applied it.
