topology2: Revisit period and buffer size settings

There is no reason to limit the buffer_size_max and the minimum limit is
periods_min * period_size_min.

On the deep buffer playback PCMs we should specify better period_size_min
since the default 192 will cause DMA overrun on start since the DMA will
fill the buffer on start.
Adjust the buffer_size_min also at the same time.
