Julia Lawall f802d6c020 ASoC: constify snd_soc_codec_driver structures 
Check for snd_soc_codec_driver structures that are only passed to
snd_soc_register_codec or memcpy (2nd arg), for which the corresponding
parameters are declared const.  Declare as const snd_soc_codec_driver
structures that have these properties.

The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
