Add support for changing mcast and beacon rate
in opensync for ath11k
Add debugfs entry for ath11k driver to set mcast,
beacon and mgmt rate.
For help:
cat /sys/kernel/debug/ieee80211/phyX/ath11k/set_rates
Eg: Set beacon rate to 12Mbps for iface wlan0 5G band
echo "wlan0 beacon 5 0x10000002" > /sys/kernel/debug/ieee80211/phy0/ath11k/set_rates
