wifi: rtw89: mcc: consider time limits not divisible by 1024

For each MCC role, time limits, including max_tob_us, max_toa_us, and
mac_dur_us, are calculated if there are NoA attributes. The relation
between these time limits is "max_dur_us = max_tob_us + max_toa_us".
Then, the unit is converted from us to TU. However, originally, each
time limit was divided by 1024 independently. It missed to consider
the cases that max_tob_us or max_toa_us is not divisible by 1024. It
causes the result breaks "max_dur (TU) = max_tob (TU) + max_toa (TU)".
Finally, when MCC calculates pattern parameters based on these kinds
of time limits, it might not perform well.
