Replace snd_soc_register_card with devm_snd_soc_register_card.
With this change, we can delete the empty remove functions.

CONFIG_HOTPLUG is going away as an option. As result the __dev*
markings will be going away.
Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst,
and __devexit.

Previously, the ASoC 'platform' (PCM/DMA) object was instantiated via a
platform_device. This didn't represent the hardware well, since there
was no separate hardware associated with this platform_device; it was a
virtual device with sole purpose to call snd_soc_register_platform().
This change removes the platform_device completely. Each Samsung DAI now
registers the ASoC 'platform' itself. Machine drivers are adjusted for
the new 'platform' name.

Allow custom accessory identification mechanisms to make use of the MICDET
support in the device.

Since we only need to clock AIF2 when it's actively in use start up the
FLL for it using a supply widget which supplies AIF2CLK. This both makes
the sequencing more robust and ensures we minimise power consumption.

Connect the WM1250-EV1 baseband simulator on Littlemill systems up to
the CODEC AIF2 using the new CODEC<->CODEC link support, allowing a wider
range of use cases to be represented.

The WM8994 has a different accessory detect architecture, call its setup
function too. We ignore the errors and the driver will check for chip type
so it's safe to call the setup functions for both architectures.

Missed .owner of struct snd_soc_card will prevent the module from being

Littlemill has one analogue microphone on the board (connected to IN1LN)
and an array of four DMICs connected to both DMICDAT lines. The biases
can be selected by jumpers but pick the default jumper fit.

The board supports CODECs that won't work with this but the CODEC driver
will check to see if it's running on the right chip for us.

The Littlemill audio card supports a number of pluggable miniboards,
normally for the WM8994 family of devices. As all these devices look
mostly the same from an external configuration point of view and are
runtime enumerable we can write a standard machine driver which will
work out of the box with any of them. Start doing that with the bare
bones of a driver, only supporting AIF1.
Future patches will flesh this out to be more fully featured.
