Allow all the CODEC drivers to be built without a machine driver in order
to facilitate testing of subsystem-wide changes and gain better coverage
from automated testing efforts. This also helps things like the generic
OpenFirmware machine driver for PowerPC.

Currently AC97 CODECs are not included since the current setup relies
on having a controller driver available.

The error path in cs4270_probe/cs4270_remove is pretty broken:
* If cs4270_probe fails, codec is leaked.
* If snd_soc_register_card fails, cs4270_i2c_driver stays registered.
* If I2C support is enabled but no I2C device is found, i2c_del_driver
  is never called (neither in cs4270_probe nor in cs4270_remove.

Fix all 3 problems by implementing a clean error path in cs4270_probe
and jumping to its labels as needed.

Update the CS4270 ALSA device driver to use the new-style I2C interface.
Starting with the 2.6.27 PowerPC kernel, I2C devices that have entries in the
device trees can no longer be probed by old-style I2C drivers.  The device
tree for Freescale MPC8610 HPCD has included an entry for the CS4270 since
2.6.25, but that entry was previously ignored by the PowerPC I2C subsystem.
Since that's no longer the case, the best solution is to update the CS4270
driver to a new-style interface, rather than try to revert the behavior of
new PowerPC I2C subsystem.

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.
