Subject: [PATCH 2/6] ASoC: SOF: amd: remove acp_dai_probe() function

ACP SOF driver supports different audio configurations.
Explicit condition check for I2S configuration will break
other audio endpoint configurations.

acp_dai_probe() function is not required as we have
machine select logic to select the exact machine.

Remove acp_dai_probe() from existing AMD PCI driver code base.
