Subject[ 47/61] ASoC: wm8904: Fix GPIO and MICBIAS initialisation for regmap conversion
3.4-stable review patch.  If anyone has any objections, please let me know.

------------------
From: Mark Brown <broonie@opensource.wolfsonmicro.com>

commit 433897f7408b556f7dfbb98c94deea02e634d2a7 upstream.

We no longer have a flat ASoC cache so can't peer directly into the array
any more but should instead use the register I/O functions to update the
cache.
