There are two type of configuration modes that require local TSF, IBSS
and mesh for operation and also monitor mode.

For IBSS, it is use for merging of BSSID (mac address) with same SSID
name, but currently this is taking care by the following "ugly" patch.

Mesh mode needs this for more accurate synchronization purpose.

Besides, the monitor mode requires this to add extra piece of
information in radiotap header for local TSF.

32-bit is not good. It could cause problem when inter-operate with
other non-ath10k drivers with 64-bit local TSF. The better is that we
can get the 64-bit local TSF. providing high TSF and low TSF as found
in "struct wmi_comb_phyerr_rx_hd". Is this possible with current FW?
