soc-qcom-sdm845: fix pops/clicks sound via alsa buffer tuning (MR 4186)

Update some alsa buffer params to solve sound quality issues

I got working values experimentally after trying
different buffer sizes and limits and watching to pw-top
to ensure there are  no errors during playback from diffrent apps and
sinks.
