[PATCH 02/10] ASoC: SOF: amd: acp-pcm: Take buffer information directly from runtime

[Pierre-Louis Bossart]

From: Peter Ujfalusi <peter.ujfalusi at linux.intel.com>

Instead of using the values from ipc_params, take them directly from
substream->runtime.

This is in preparation of making the platform hw_params callback to be
IPC agnostic.
