ASoC: amd: Fix reference to PCM buffer address

ASoC: amd: Fix reference to PCM buffer address

BugLink: https://bugs.launchpad.net/bugs/1969110
[ Upstream commit 54e1bf9f6177a3ffbd920474f4481a25361163aa ]

PCM buffers might be allocated dynamically when the buffer
preallocation failed or a larger buffer is requested, and it's not
guaranteed that substream->dma_buffer points to the actually used
buffer.  The driver needs to refer to substream->runtime->dma_addr
instead for the buffer address.
