Currently ASoC card initialisation is completed by a function called
snd_soc_register_card(). As part of the work to allow independant
registration of cards, codecs and machines in ASoC v2 a new function of
the same name has been added so rename the existing function to
facilitate the merge of v2.

Liam Girdwood's ASoC v2 work avoids having two different ops structures
for DAIs by merging the members of struct snd_soc_ops into struct
snd_soc_dai_ops, allowing per DAI configuration for everything.
Backport this change.
This paves the way for future work allowing any combination of DAIs to
be connected rather than having fixed purpose CODEC and CPU DAIs and
only allowing CODEC<->CPU interconnections.

Currently the boiler plate code used by most ASoC codecs to provide a
placeholder for SPI access suggests making the selection of SPI a
compile time option which is suboptimal when trying to build kernels
supporting multiple systems. Change this template to suggest allowing
runtime selection instead.
Leave the drivers not yet converted to new style I2C access for now to
avoid collisions.

Convert the ak4535 codec driver to the new (standard) device driver
binding model. After this change, AK4535 devices are no longer
discovered automatically and must instead be instantiated explicitly.

Many SoC audio codec drivers have improper freeing of memory in error
paths.
* codec is allocated in the platform device probe function, but is not
freed there in case of error. Instead it is freed in the i2c device
probe function's error path. However the success or failure of both
functions is not linked, so this could result in a double free (if
the platform device is successfully probed, the i2c device probing
fails and then the platform driver is unregistered.)
* codec->private_data is allocated in many platform device probe
functions but not freed in their error paths.
This patch hopefully solves all these problems.

The AK4535 codec is included in some HP iPAQ systems.
This driver was originally written by Richard Purdie and with some bug
fixes from Milan Plzik. While out of tree it has also had some
mechanical updates for new APIs and current best practices from Liam
Girdwood, Graeme Gregory and Mark Brown.
