ASoC: SOF: Intel: hda-pcm: Place the constraint on period time instead of buffer time
Instead of constraining the ALSA buffer time to be double of the firmware
host buffer size, it is better to set it for the period time.
This will implicitly constrain the buffer time to a safe value
(num_periods is at least 2) and prohibits applications to set smaller
period size than what will be covered by the initial DMA burst.
