ASoC: SOF: ipc4-topology: Correct the minimum host DMA buffer size
[ Upstream commit a7fe5ff832d61d9393095bc3dd5f06f4af7da3c1 ]
The firmware has changed the minimum host buffer size from 2 periods to
4 periods (1 period is 1ms) which was missed by the kernel side.
Adjust the SOF_IPC4_MIN_DMA_BUFFER_SIZE to 4 ms to align with firmware.
