    ASoC: SOF: ipc4-pcm: Use consistent name for snd_sof_pcm_stream pointer
    
    [ Upstream commit 965e49cdf8c19f21b8308adeded3a8139cff5c84 ]
    
    Throughout the file the pointer for snd_sof_pcm_stream is named either
    'stream' or (wrongly) 'spcm' which confuses the reader.
    
    Use 'sps' for the pointer name as it is the most common name used in SOF
    codebase.
