Series wifi: ath12k: some improvement to RX throughput | expand

Commit Message

Currently the maximum block ACK window size supported is 256.
This results in that, when connected to an AP which supports
larger BA sizes like BA512 or BA1024, only BA256 is
established, leading to a lower peak throughput.

So add support for BA1024, this is done by allocating a larger
REO queue and advertising IEEE80211_MAX_AMPDU_BUF_EHT support
to MAC80211.

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4
