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.
