Tests show frequent suspend/resume(frequent poweroff/on ad1836 internal
components) maybe make ad1836 clock mode wrong sometimes after wakeup.
This patch reset/restore ad1836 clock mode while executing PM, then
ad1836 can always resume to right clock status.

The WM8955 is a low power, high quality stereo DAC with integrated
headphone and loudspeaker amplifiers, designed to reduce external
component requirements in portable digital audio applications. This is
an initial driver implementing support for the majority of the
functionality in the device, currently OUT3 is not supported.

This original driver was created by Dialog Semiconductor,
and cleanuped by Kuninori Morimoto.
Special thanks to David Chen.
This became very simple ASoC codec driver,
and it is tested by EcoVec24 board.

The driver can be 'generalized' a bit by not hardcoding '2'(the number of
I2Sv3 controllers that the driver can handle) at many places, instead we
define a macro for it. That makes it easier to increase number of controllers
by changing the parameter at just one place, this will be useful when there is
support for newer SoCs, which have the same controller, only more in number.

sizeof(codec->reg_cache) is just the size of the pointer. Elsewhere in the
file, codec->reg_cache is used with sizeof(wm8900_reg_defaults), so the
code is changed to do the same here.
A simplified version of the semantic patch that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

There are build errors when building for some of the omap2/3 boards without
enabling sound:
sound/built-in.o:(.data+0x43bc): undefined reference to `soc_codec_dev_tlv320aic23'
sound/built-in.o:(.data+0x43cc): undefined reference to `tlv320aic23_dai'
Confused me quite a bit since the drivers that had references to the
codec weren't enabled. Turns out the Makefile was using the wrong
config option to enable them. Patch below.

The WM8904 is a high performance ultra-low power stereo CODEC
optimised for portable audio applications, with features including
a class W amplifier, FLL with free running mode, Mobile ReTune and
ground referenced headphone and line outputs.
Support for some features, most particularly the digital microphone
interface, is not yet present.

Add clock enable and disable calls to resume and suspend respectively.
Also add a member to the audio device data structure which tracks the clock
status.
Tested on DA850/OMAP-L138 EVM. For the purpose of testing, the patches[1] which
add suspend-to-RAM support to DA850/OMAP-L138 SoC were applied.

But this style will be broken
if SuperH come with multiple FSI blocks in future.

Driver callbacks for Runtime PM are empty because

When we get a stream suspend event force the power down since otherwise
the stream would remain marked as active. In future we'll probably want
to make this stream-specific and add an interface to make the power down
of other widgets optional in order to support leaving bypass paths
active while suspending the processor.
