ASoC: SOF: ipc4-topology: Correct the minimum host DMA buffer size

Browse Source 
[ Upstream commit a7fe5ff832 ]

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.
