ASoC: pxa: constify snd_pcm_ops structures
snd_pcm_ops are not supposed to change at runtime. All functions working with snd_pcm_ops provided by <sound/soc.h> work with const snd_pcm_ops. So mark the non-const structs as const. Signed-off-by: Arvind Yadav <arvind.yadav.cs@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org>
