qcacmn: Add support to handle PEER_OPER_MODE_CHANGE event

Firmware sends PEER_OPER_MODE_CHANGE event to host in SAP
mode when a connected client indicates upgrade/downgrade
of its bandwidth.
Host needs this data as any further SAP bandwidth
upgrade/downgrade should honor the indicated bandwidth for
that specific peer.
