wifi: ath12k: dynamically update peer puncturing bitmap for STA

Every time EHT Operation element changed, mac80211 will parse it and
extract the valid puncturing bitmap according to the bandwidth.

Current driver only update puncturing bitmap to firmware as vdev
parameter. Which can only meet the needs of AP. But STA will also use
it as peer parameter. If only update as vdev parameter, might cause
firmware crash. QCN9274 is the same.

So update bandwidth and puncturing bitmap as peer parameters once they
changed for STA. Then send them to the firmware by WMI event.

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
