Karthikeyan Periyasamy 7b0c70d92a ath11k: Add peer rhash table support ...

When more clients (128) are connected, the UL data traffic
KPI measurement is low compared to single client. This issue
is due to more CPU cycles spent on the peer lookup operation
with more clients. So reduce the peer lookup operation by
modifying the linear based lookup operation into the rhash
based lookup operation. This improve the peak throughput
measurement. Since this is a software algorithm change, it is
applicable for all the platforms.

TCP UL 128 Clients test case Observation (64bit system):
Previous: ~550 Mbps
Now	: ~860 Mbps

Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.5.0.1-01067-QCAHKSWPL_SILICONZ-1
