ASoC: mediatek: mt8195: update audio tuner settings
Audio tuner is used to handle clock drift between 26M and APLL domain.
It's expected when abs(chg_cnt) equals to upper bound, tuner updates pcw
setting automatically, and then abs(chg_cnt) decreases.
In the stress test, we found abs(chg_cnt) possibly equals to 2 at the
unexpected timing. This results in wrong pcw updating.
Finally, abs(chg_cnt) will always be larger than upper bound,
As a result, we update the upper bound to 3 to handle the corner case.
