wifi: rtw89: phy: limit AMPDU number for RA try rate

When RA (Rate Adaptive) does try higher rate, a TRY bit is flagged, and
hardware will reference registers configured by this patch as maximum
number of AMPDU. To prevent aggregate too many MPDU over peer's capability
causing loss in peer side, set the minimum values across all stations and
TID since there is single one register per hardware band. Consider MLD
case, a BA session can run across two hardware bands, so set the same
value as well.
