[PATCH 01/17] ASoC: amd: renoir: acp3x-pdm-dma: remove unnecessary assignments

[Pierre-Louis Bossart]

cppcheck warning:

sound/soc/amd/renoir/acp3x-pdm-dma.c:132:17: style: Variable
'pdm_dma_enable' is assigned a value that is never
used. [unreadVariable]
 pdm_dma_enable = 0x00;
                ^
sound/soc/amd/renoir/acp3x-pdm-dma.c:156:18: style: Variable
'pdm_dma_enable' is assigned a value that is never
used. [unreadVariable]
  pdm_dma_enable = 0x00;
                 ^

indeed those values are never used because the timeout is reset.
