With generic AC97 ASoC glue driver (codec/ac97.c), we get following warning when
the device is registered (slightly stripped the backtrace):

kobject (c5a863e8): tried to init an initialized object, something is seriously
                    wrong.

This happens because the generic AC97 glue driver creates its codec->ac97 via
calling snd_ac97_mixer(). snd_ac97_mixer() provides own version of
snd_device.register which handles the device registration when
snd_card_register() is called.

To avoid registering the AC97 device twice, we add a new flag to the
snd_soc_codec: ac97_created which tells whether the AC97 device was created by
SoC subsystem.

It is not needed since snd_ac97_mixer() will create a new ac97 object for us.
Removing the call also fixes a memory leak since codec->ac97 is set to NULL at
the beginning of snd_ac97_mixer().

Dramatically reduce the code size for the WM8962 register defaults table
by switching to explicitly initialise only defined registers, relying on

Similar treatement for the register access table will come later and will
produce a similarly dramatic code size shrink.
