Subject: [PATCH v6 3/3] ath11k: Add support for beacon tx mode

Add support to configure the beacon tx mode in
the driver.

Beacons can be sent out in burst(continuously in a single shot
one after another) or staggered (equally spread out over beacon
interval) mode.

Use the below configuration in the hostapd/wpa_supplicant
for AP/MESH mode to configure the beacon tx mode.

"beacon_tx_mode=N", where N = 1 for STAGGERED beacon mode
and N = 2 for BURST beacon mode.

Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.5.0.1-00480-QCAHKSWPL_SILICONZ-1
