ASoC: SOF: ipc4/Intel: Place constraint on the PERIOD_TIME based on the DSP host buffer size (which is provided in ms) fro playback #4858

Hi,

when a playback starts, the first DMA burst will fill the DSP host buffer. If user space asks for shorter period size then this burst and starts a playback with less than the burst size of the DSP then it will immediately xrun (DMA copies uninitialized data to DSP).

Place a constraint on the minimum period time (which will be forcing safe period size) to avoid such issue.

Changes since v1:

Fix misspelled word in commit 2

Merged to #4851 to have all delay related fixes in one place (for make it easier to pick them for upstream)
