    ASoC: rcar: dma: remove unnecessary "volatile" · 9986943e

    commit 2a3af642eb20("ASoC: rcar: clear DE bit only in PDMACHCR...")
    added rsnd_dmapp_bset(), but it used copy-paste. Thus, it had
    unnecessary "volatile", and had below warning on x86.
    This patch fix it.
    
       sound/soc/sh/rcar/dma.c: In function 'rsnd_dmapp_bset':
    >> sound/soc/sh/rcar/dma.c:463:21: warning: passing argument 1 of \
       'ioread32' discards 'volatile' qualifier from pointer target \
       type [-Wdiscarded-qualifiers]
         u32 val = ioread32(addr);
