wifi: rtw89: 8852c: enlarge polling timeout of RX DCK
The range of calibration time of RX DCK is quite wide from ~40us to
~1300us by experiments, and probability is about 0.1% for the cases larger
than 1000us. Though it can retry calibration and get positive result, it
will spend more time. Therefore, enlarge it to avoid warning and duplicate
calibration.
