Introduce debugfs entry to select beacon tx mode to
staggered or bursted mode. In staggered mode, software beacon
alert will be evenly distributed for each beaconing interfaces
by (beacon intval / number of vif). In bursted mode, batch of
beacons will be sent out as batch at beacon interval.
By default, staggered mode is selected.
To select bursted mode
echo 1 > /sys/kernel/debug/ieee80211/phyX/ath10k/beacon_tx_mode
For staggered mode,
echo 0 > /sys/kernel/debug/ieee80211/phyX/ath10k/beacon_tx_mode
