[PATCH 2/2] ASoC: amd: yc: fix memory leak in acp6x_pdm_dma_close()

[wangdich9700]

From: wangdicheng <wangdicheng@xxxxxxxxxx>

acp6x_pdm_dma_close() does not free the runtime->private_data buffer
allocated in acp6x_pdm_dma_open(). Add the missing kfree.

Fixes: 7610174a5bfe ("ASoC: amd: add acp6x pdm platform driver")
