ASoC: ux500_pcm: Use the same snd_pcm_hardware for playback and capture
The snd_pcm_hardware structs for playback and capture in the ux500 PCM are identical, so remove one of them and use the same snd_pcm_hardware struct for both playback and capture. Also move the defines used to initialize the snd_pcm_hardware fields from ux500_pcm.h to ux500_pcm.c since that's the only place where they are used. Also drop the assignment of the snd_pcm_hardware struct to runtime->hw since that is what the call to snd_soc_set_runtime_hwparams() right above it already does, so the second assignment is redundant.
